At least seven people were Monday killed by a suicide attack on a meeting of several thousand Islamic scholars in Afghanistan who were discussing issuing a fatwa, or religious ruling, against such attacks.

The bomber, who was on foot, detonated the explosives at around 11:30 a.m. local time near the Loya Jorga hall at the Kabul Polytechnic University, Interior Ministry spokesman Najib Danish told CNN. At least nine more people were injured in the blast, which targeted Afghanistan’s Ullema Council.

It is not yet known who was behind the attack.

Terrorists have killed dozens of people in Kabul in recent months, including 10 journalists in April.

On May 30, it was the turn of the Interior Ministry to be targeted. A policeman was killed along with a suicide bomber and all seven gunmen.

Both attacks were claimed by the Islamic State.

Meanwhile, the Taliban has also increased attacks across the country. The US-backed government in Kabul has been found itself increasingly struggling against terrorist assaults since the withdrawal of the majority of NATO troops in 2014.
