The US claims to have killed one of the leaders of the Al-Qaeda terrorist network in Syria.

Abdul Hamid al-Matar was killed in a drone attack in northwest Syria, a spokesman for the US Central Command said on Friday.

According to current knowledge, civilians were not harmed in the attack near Suluk.

The killing of al-Matar will affect al-Qaeda's ability to "plan and carry out further attacks worldwide," said the army spokesman.

The extremist organization continues to "pose a threat to the United States and our allies."

Al-Qaeda is using Syria as a retreat to regroup and plan missions abroad.

Drone attack took place two days after the attack on the air force base

According to the Pentagon, the USA had already killed an al-Qaida commander in a US air strike in the Idlib region in northwest Syria at the end of September.

The drone attack on al-Matar came two days after an attack on an air base in southern Syria used by the US-led anti-IS coalition.

Around 500,000 people have been killed since the civil war in Syria began in 2011.

More than 6.6 million others sought refuge abroad.
