BEIRUT (AP) — The latest on Syria's civil war and the stalled peace talks in Geneva (all times local):

2:40 p.m.

Syrian rescue workers and an opposition monitoring group say at least 10 people were killed in airstrikes in rebel-controlled areas in the deeply contested city of Aleppo.

Ibrahem Alhaj from the Syrian Civil Defense, which conducts search and rescue operations in rebel-held areas, says government jets carried out some 40 airstrikes on Tuesday in rebel-controlled areas in the city that left 10 people killed and 40 wounded.

A video shows Civil Defense volunteers pulling the body of a toddler from under the rubble as a gray plume of dust covers an entire street and people are seen covering their mouths as they run away.

Earlier on Tuesday, five members of the civil defense organization were killed when an airstrike hit their training center in the town of Atareb, west of Aleppo.

The Britain-based Syrian Observatory for Human Rights puts the death toll in rebel-held areas in Aleppo city at 11, suggesting it could rise further. The Observatory says the airstrikes are continuing.

1:10 p.m.

The U.N. envoy for Syria will brief the U.N. Security Council on the latest round of Geneva peace talks, which have stalled after the main opposition group largely pulled out of the negotiations.

U.N. spokesman Ahmad Fawzi says the envoy, Staffan de Mistura, will address the council via video conference Wednesday after ending the third session of on-and-off talks this year.

Fawzi spoke ahead of meetings Tuesday in Geneva, including one between de Mistura and the Syrian government delegation and one by a task force that monitors Syria's increasingly wobbly cease-fire.

The opposition High Negotiations Committee suspended its role in the formal talks in Geneva last week to protest alleged cease-fire violations, a drop in humanitarian aid deliveries to Syrians and no progress in winning the release of detainees in Syria.

11:25 a.m.

A Syrian rebel-run first responder service says an airstrike has hit its training center in northern Syria, killing five personnel.

The Syrian Civil Defense, which conducts search and rescue operations in rebel-held areas, says the attack took place in the town of Atareb, west of the city of Aleppo, on Tuesday morning.

The organization, also known as the White Helmets, has received global praise for its rescue operations in Syria.

The Britain-based activist group Syrian Observatory for Human Rights has confirmed the strike. The Observatory, a monitoring group that relies on a network of activists inside Syria, also reported that separately from the attack on White Helmets, pro-government forces also launched two rockets into Atareb on Tuesday.
