In 1124, he was invited to defend Tyre, the only port the Muslims used in Syria against the attacking Crusaders. In the meantime, Belek was besieging Manbij, after he imprisoned its emir Hassan al-Ba'labakki ibn Gümüshtigin who pledged allegiance to Joscelin I, in which he managed to capture the city but the castle was still controlled by the defenders led by Hassan's brother Isa. A Crusader force led by Joscelin I tried to help the defenders, but Belek forced them to retreat to Turbessel (now"Tilbaşar"), and maintained the siege until he was hit and killed by an arrow on 6 May 1124. His cousin Husam ad-Din Timurtash ibn Ilghazi took his dead body back to Aleppo on the next day. Shortly after his death Harput was annexed by the Artukids of Hasankeyf. Nevertheless, in 1185 another beylik was founded by Artukids in Harput.
