Al Qaeda leader Ayman al-Zawahiri exhorted his fighters to find out who killed his chief representative in war-torn Syria, where militants have had a strong presence and strong rivalries amid the country's civil war. Two suicide bombers in Aleppo killed Khaled al-Suri in February when they blew themselves up inside a compound used as a headquarters. Al-Zawahiri, in a recorded message posted on a militant website and uploaded on YouTube, deplored the action and called it "sedition." "All Muslims should not help those who blow up the headquarters of the holy fighters or those who send them car bombs and human bombs, and to stop supporting it in any way," the speaker said.
