The brother of the Palestinian bomber who blew himself up killing five people at a shopping mall in Israel on Monday was employed as a Math teacher with a well-known English school in Kuwait, sources told the Arab Times on Sunday. Citing personal reasons, the teacher identified as Pervez Abu Saada left the country for an unknown destination a few days ago. The school refused to comment on the incident. Earlier news reports said the bomber Lutfi Abu Saada hailed from a village near Tulkarm in the West Bank. Described as dynamic and efficient, the teacher is a British citizen. It was not immediately clear whether his family was residing with him in Kuwait. A source at the school said âthe teacher decided to leave of his own free will due to family commitments. He was a good teacher and his work is appreciated by all.â In recognition of his contribution to the school, the teacher was to don the mantle of Deputy head of the institution before the tragedy struck. According to reports, the bomber carrying a bag was challenged by police when he tried to enter the mall. He was reported to have smiled before blowing himself up.
