A senior leader of a key Islamist group in Syria has been killed in a coalition airstrike near Idlib, the group confirmed on Monday after the Pentagon announced that it had targeted him.

Ahmed Salameh Mabrouk, an Egyptian also known by his nom de guerre Abu Faraj al-Misri "was martyred after a coalition air strike in the west of Idlib province," Jabhat Fateh al-Sham said in a statement on the Telegram app.

Born in 1956 in the suburbs of Cairo, Mabrouk was known as a veteran al-Qaeda leader and a Jabhat Fateh al-Sham (Front of the Conquest of Syria) commander.
