(CNN) -- Reeling from his doomed cease-fire plan that disintegrated in hours, international envoy Lakhdar Brahimi met Monday with Russia's foreign minister on what to do about the Syrian civil war.
But no easy answer emerged.
It was Brahimi's first meeting with Foreign Minister Sergey Lavrov as U.N.-Arab League envoy to Syria, a position he inherited after other world diplomats also failed to stop more than a year of relentless bloodshed.
Diplomacy with Russia is a delicate dance. Russia, along with China, has repeatedly vetoed attempts at the U.N. Security Council to take stronger action against Syrian President Bashar al-Assad.
Many have accused Russia of backing the Syrian government, but Russia says it just wants a political solution for Syria determined by its own people.
Brahimi had pushed for government forces and rebels to stop fighting during Eid al-Adha, a major Muslim holiday that began Friday and ends Monday. Yet the violence continued unabated.
At least 104 people have died Monday in fighting across Syria, according to opposition activists.
Brahimi said neither side of the crisis is showing signs of backing down.
"The government says they are fighting terrorists and only terrorists, and that it is their duty to do so -- to protect their people. And the other side says we're fighting a very cruel government that is persecuting us, and we're defending ourselves," Brahimi said after the meeting.
He recalled speaking with a woman who has one son in the Syrian military and another son in the rebel Free Syrian Army.
"If that is not civil war, I don't know what is," Brahimi said.
In other developments:
Fears of a regional war surfaced once again when shelling from Syria landed across the Turkish border into Hatay province, Turkey's Anadolu Agency reported.
The shelling apparently came from fighting in the Syrian town of Harim. Turkey fired back.
There was no immediate word on casualties from the cross-border incident.
Turkey and Syria have traded artillery rounds along their borders sporadically for weeks.
The Hatay governor's office said a mortar shell landed in a Turkish field two weeks ago. Turkish border forces retaliated immediately.
The office said that there were no casualties in that incident.
Tensions between the two countries are palpable. Turkey, once a friend of Syria's, now opposes al-Assad's government. Turkey also hosts more than 100,000 Syrian refugees and opposition leaders.
In Syria on Monday, at least six people were killed in an attack in the Damascus countryside, according to state-run media SANA. The area is a pro-Assad stronghold.
