Syrian rebels including Al-Qaeda's former affiliate vowed on Tuesday to avenge the deaths of dozens of people in a suspected gas attack, calling on allied fighters to "ignite the fronts."

"We call on all the fighters of Sham (Syria) to ignite the fronts," the Tahrir al-Sham alliance said in a statement posted online.

At least 58 people, including 19 children, were killed early Tuesday morning after air strikes on a town in northwest Idlib Province, most of which is held by Tahrir al-Sham.
