An air strike by the US-led coalition has killed Sanafi Al-Nasr, a Saudi citizen and the leader of an Al Qaeda offshoot called the Khorasan Group, a Pentagon spokesman said on Sunday.

The Pentagon said Al-Nasr organised routes for new recruits to travel from Pakistan to Syria through Turkey and played a significant role in the group's finances.

He was killed in an air strike on Thursday in northwest Syria, it said. -Reuters
