Tawhid Brigade's head, Abdul-Qader Saleh dies of his wounds

Tawhid Brigade's head, Abdul-Qader Saleh, has been died of his wounds in Turkish hospital after 2 days of being attacked by Assad airstrike with top rebel leaders, well-informed source told Zaman Alwasl.

A coalition member spoke to Zaman Alwasl on condition of anonymity assured killing of Salh since two days.

Saleh was injured on Friday in an air strike by Assad's forces on Aleppo, activists said, in a setback to rebels defending the city against a loyalist attack.

Aleppo, Syria's commercial hub and most populous city before the uprising against Assad erupted in 2011, has been witnessing heavy fighting since Assad's forces, backed by Shi'ite militia from Iraq and the Lebanese party Hezbollah, launched an offensive two weeks ago to retake rebel-held areas in the city, according to Reuters.

The opposition Aleppo News Network said Friday in a statement that the raid on Thursday targeted an army base that rebels had captured, killing commander Youssef al-Abbas of al-Tawhid Brigades, one of the biggest armed opposition groups.

Tawhid's leadership was holding a meeting in the base when the raid occurred, the statement said.

Saleh was taken to a hospital in Turkey, 45 kms (28 miles) to the north, along with Abdelaziz al-Salameh, another top commander, the statement said.
