Syrian rebels started leaving the southern province of Daraa Tuesday as part of a Russian-brokered truce aimed at ending the worst fighting in the region in years, a war monitor said.

An explosion shook the base of an al-Qaida-linked group in northern Syria on Tuesday, killing and wounding dozens of fighters, opposition activists said.

Daraa, retaken by government forces in 2018, has emerged as a new flashpoint in recent weeks as government forces tightened control over Daraa al-Balad, a southern district of the provincial capital that is considered a hub for former rebel fighters.
