In two separate incidents in 1989, Hamas kidnapped and murdered two Israeli soldiers, Sgt. Avi Sasportas and Cpl. Ilan Saadon.
The terrorist responsible for these murders, Mahmoud Al-Mabhuh, was one of Hamas' Al Qassam Brigades co-founders. Some time later he ran away from Gaza and went off to live in the UAE.
He just died of cancer in a hospital there.
