Among the 49 injured civilians were 12 children and 11 women, according to the group.

Syria has been carrying out airstrikes routinely in the area against what the regime calls terrorists.

Heavy artillery shells and rocket launchers were unleashed upon more than 15 cities, towns, and villages across Idlib and the Aleppo countryside in northwest Syria. Notably, markets, schools, public facilities, and humanitarian workers were targeted in these attacks, the White Helmets said in a statement.

On Wednesday, the group reported airstrikes targeting a school in Sarmeen city in the eastern countryside of Idlib, resulting in the death of one child and injuries to six civilians, including three girls – with one being an infant – and two women.

Northwest Syria has witnessed its third consecutive day of deadly bombardment, the group said on Thursday.

Turkey strikes Kurdish targets in Syria

Meanwhile, at least 11 people were killed on the other side of the country Thursday by Turkish airstrikes targeting Kurdish-controlled areas of northeastern Syria, according to a statement by Kurdish security forces in the region.

“The Turkish state launched on Thursday a series of attacks on our regions with more than 15 drones penetrating the airspace of northeastern Syria, and again targeted many positions, infrastructure, service facilities, and gas and oil stations, resulting in death and injuries. Its aggression also affected areas populated by civilians,” said Asayish, the Kurdish internal security force.

Turkey’s military has launched a series of airstrikes against Kurdish targets in Syria and Iraq following a deadly bombing in the Turkish capital on Sunday. The attack in Ankara was claimed by the Kurdistan Workers’ Party (PKK), which has carried out a decades-long insurgency against the government and is classified as a terrorist organization by Turkey, the United States, and the European Union.

In a separate incident, a US fighter jet shot down an armed Turkish drone in Syria that was operating near US military personnel and the US-backed Syrian Democratic Forces (SDF), officials familiar with the incident told CNN Thursday.

The backbone of the SDF is the Kurdish People’s Protection Units (YPG), which Turkey says is a wing of the PKK.

The US assessed the armed drone as a potential threat, and issued more than a dozen warnings before shooting it down, the officials said, adding that several drones made repeated approaches toward US troop positions.

It is unclear how the warnings were issued. There were no reports of US casualties, an official said.

The Turkish Defense Ministry said that the drone didn’t belong to the Turkish armed forces, Reuters reported. CNN has reached out to the Turkish government for comment.
