UK Foreign Secretary Liz Truss said on Sunday she was “horrified” by Russia’s bombing of a school in Luhansk, Ukraine, “resulting in the deaths of innocent people sheltering from Russian bombardment.”
“Deliberate targeting of civilians & civilian infrastructure amounts to war crimes. We will ensure Putin’s regime is held accountable,” she tweeted.
Ukrainian authorities in Luhansk said on Sunday that 60 people were “most likely dead” after a Russian aircraft dropped a bomb on the school where civilians were sheltering on Saturday.

US First Lady Jill Biden made an unannounced trip on Sunday to Uzhhorod, Ukraine, a small city in the far southwestern corner of Ukraine.
At a converted school that now serves as temporary housing for displaced citizens, Biden met with Ukraine's First Lady Olena Zelenska, who has not been seen in public since the start of the war on Feb. 24.
The first lady is the latest high profile American to visit the war torn country in recent weeks.
“I wanted to come on Mother’s Day,” said Biden to her Ukrainian counterpart, the two women seated at a small table in a classroom of a former school that is now a source of temporary housing for displaced Ukrainians, including 48 children.
“We thought it was important to show the Ukrainian people this war has to stop. And this war has been brutal.” Biden added, “The people of the United States stand with the people of Ukraine.”
Zelenska, who early on in the Russian invasion sent a letter to Biden, has exchanged correspondence in recent weeks, US officials tell CNN.

In the midst of fierce shelling by Russian forces, a 15-year-old drove several people who had been injured out of the frontline town of Popasna in Luhansk.
During the journey, the car was shot at and she was wounded in the legs, but she kept driving.
The girl's first name is Anastasia; as she is a minor CNN is not giving her full name. One of her teachers confirmed her identity to CNN.
Not only did Anastasia have to drive through a battlefield; there were mines and bodies on the road out of the town, which was on the verge of falling to Russian forces.
She was among the last civilians to try to escape Popasna, much of which has been destroyed in weeks of fighting.
Anastasia said she wanted to help evacuate two men who had been wounded. Two other people were also in the car.
“And I had to get behind the wheel and drive to Bakhmut,” she said — a journey of some 20 miles through countryside that is often under fire by Russian artillery and planes.
She had driven before; her deceased mother had taught her, she said. But it was hardly any preparation for the escape from the hellish situation in Popasna.
“We have a bridge, then you go down, and then up. And there were mines there in a checkerboard pattern. There was no way to get through,” she said.
“But I somehow drove through. Further along there was the corpse of a woman,” she said in an interview conducted in by the Lviv hospital and provided to CNN.
Anastasia added, “And then there was a turn to the right and we were fired upon, my feet [were hit]. There was almost nothing I could do, the car stalled.”
“When they started shooting, the car stopped and they fired. Then I started the car and we drove on again," she said.
The car staggered forward a short distance but then stalled again because the battery had been shot through by a bullet.
The teenl and the other occupants of the car were picked up by the Ukrainian military and taken to the hospital in Bakhmut.
She said she had two bullet wounds to her knee and foot.

First Lady of the US Jill Biden visited the Tomasikova Street School in Slovakia on Sunday to mark Mother's Day and meet with students and teachers.
Dr. Biden was met with bread in salt, a welcome tradition in Slovakia and other Slavic countries.
Students can be seen making art projects for Mother's Day and one student gave Dr. Biden what he made. Biden then stopped by different tables around the classroom, meeting with the children and their mothers.
"The hearts of the American people are with the mothers of Ukraine," Biden said, according to the pool, as she wished one table a happy Mother's Day.
The First Lady asked the mothers if they had support, to which one woman responded, per the pool (which was translated): "We have the support of Slovakia. Slovakia helped us a lot.”
Reporters, after being invited to ask questions, asked what they tell their children about what is going on.
“They need to understand why we are here and why we receive help — why are we separated from our husbands. They need to understand what is going on," one woman said through a translator, according to the pool.
Asked what it means to them to have the first lady of the US visiting, one woman said, per the pool, with the help of a translator: "It means support for us."
She added: "We are very tired. This is emotional support for us.”
Prior to her visit to the school, Dr. Biden visited the Kosice Aid Center where she met with Ukrainian refugees and volunteers.

The first electric train in weeks arrived at the Irpin railway station from Kyiv on Saturday, after crossing a newly rebuilt bridge that was destroyed in the war.
The bridge, destroyed during the Russian occupation, was one of many key links between Kyiv and western Ukraine — its destruction forced trains to take a longer detour. The steel bridge was rebuilt in a matter of weeks, a process that would have taken months before the urgency of war. Hundreds of railway workers and military worked on the restoration.
The restored span is only wide enough for one set of tracks. A second bridge next to the newly-rebuilt one is still under construction. Workers told CNN they worked for 25 days, with crews on site virtually around the clock.
The inaugural train across the span carried the infrastructure minister, the mayor of Irpin and a senior rail executive on a 25-minute journey from Kyiv. According to Oleksandr Kubrakov, minister of infrastructure of Ukraine, more than 300 rail and road bridges across the country have been destroyed since the war began.
Work is currently underway to rebuild at least 50 of them. Ukrainian Railways has been indispensable during the war — shuttling supplies in, and civilians out of the more dangerous parts of Ukraine. It has taken an enormous effort to keep trains on the tracks; the railway says that 20% of the system is either no longer controlled by Ukraine, or cut off by bombing.
Among the workers are not only railway workers from Kyiv and Irpin, but also workers from Lviv, who came to help their colleagues.
"These are not someone’s bridges, they are all Ukrainian and we have to restore them all," said one worker.
Almost everyone CNN spoke to knows of railroad workers who died during the occupation. During the war, 118 employees of Ukrzaliznytsia were killed — some while fighting on the front lines, others were just showing up for their regular jobs.
One worker, Vadim Levitsky, 45, hardly held back tears while explaining that many of his colleagues were under occupation.
"We tried to help them at every opportunity. We were very glad that they survived. I’m happy that these days I can meet with them and talk to them," Levitsky said.
"We carried out surveys of stakes under shelling and more than once heard explosions not far from them," Levitsky added.

Ukrainian fighters battling Russian armed forces at the besieged Azovstal steel plant in Mariupol have vowed to continue fighting.
"Surrender is not an option," members of Ukraine’s Azov Regiment said, speaking at an online news conference.
The fighters called on the international community to help evacuate injured soldiers from the plant, which is the last holdout from Russian forces in the port city.
Reportedly speaking from a hideout location within the Azovstal premises, Azov soldier Illia Samoilenko, said “surrendering is unacceptable for us. And chances of surviving for us if surrender to Russians tends to zero.”
He said that there are “dozens” of civilians still inside the plant.

A convoy of civilian vehicles trying to escape fighting near the city of Kharkiv was fired upon, killing several people, the Kharkiv region police said. Others are missing.
Serhiy Bolvinov, chief of the investigation department, said police had lost contact with the convoy a few days ago.
There were 15 cars traveling near the village of Staryi Saltiv, which has seen heavy fighting in recent days as Ukrainian forces launch a counter-attack against the Russians east of Kharkiv.
At the time, the convoy was trying to reach territory controlled by the Ukrainians, Bolvinov said.
"Due to the ongoing combat, it was not possible to reach the place of the column," Bolvinov said.
The wreckage of the convoy was found on Friday, he said. Having arrived at the scene, investigators found a broken enemy tank and the bodies of two Russian soldiers.
A further 300 meters away, six cars with bullet holes were found. Four corpses were found in the cars and, according to Bolvinov, they appeared to be some of the civilians who had been in the convoy.
The remains of a 13-year old girl had been positively identified, he said.
Bolvinov gave no details about what may have happened to other vehicles in the convoy.
