Syrian state television said Friday night that the leader of the jihadist Al-Nusra Front had been killed, but state news agency Sana quickly withdrew an alert saying the same thing. \"The terrorist Abu Mohammed al-Jawlani, chief of the Al-Nusra Front affiliated to Al-Qaeda, has been killed in the campaign in (the northwestern province of) Latakia,\" the television said, without providing details. No confirmation was immediately available from other sources.
