Gaza---Relatives of a top Hamas security official in the Gaza Strip say he was arrested at Cairo airport while returning from a pilgrimage to Saudi Arabia. Egyptian officials confirmed Sunday a member of Hamas' military wing had been arrested before the weekend at Cairo's airport because his name was on a wanted list for using falsified travel documents. The officials and relatives spoke on condition of anonymity because of the sensitivity of the subject. Mohammed Dababish is a top official in Hamas' internal security unit, which oversees intelligence matters in Gaza. Hamas officials declined comment. Egypt has arrested a string of Hamas figures since an Egyptian soldier was killed in a border shooting early this year.
