A Syrian air strike has killed a senior commander of the Islamist Liwa Al-Tawhid rebel brigade in Aleppo and wounded its chief and another leader, a watchdog said Friday.
Four more rebel chiefs were killed in other incidents, three in the northern Aleppo province and the fourth in Homs to its south, the Syrian Observatory for Human Rights said.
Yussef al-Abbas, known as Abu al-Tayyeb, was intelligence chief for Liwa al-Tawhid and was killed in a strike Thursday on an army base captured by the rebels a year ago, the Britain-based Observatory said.
The brigade's top commander, Abdelkader Saleh, and another senior figure of the group, Abdelaziz Salameh, were wounded.
Following the attack, Liwa al-Tawhid arrested 30 people accusing them of being informers for the regime of President Bashar Assad.
