Dozens of gunmen stormed the home of deposed Gaza security chief Moussa Arafat before dawn Wednesday and shot him dead, witnesses and police said.
Arafat, 66, a cousin of the late leader, Yasser Arafat, was fired earlier this year by Palestinian leader Mahmoud Abbas. It was not immediately clear who the gunmen were.
Moussa Arafat was linked to corruption charges and had many powerful enemies, and it was thought that his killing was related to internal conflicts.
The gunmen shot at his house in Gaza City and fired rocket-propelled grenades, then stormed the house, killing Arafat. His oldest son, Nimhel, who is a senior security official, was either kidnapped or escaped, police at the scene said.
An Associated Press Television News cameraman saw Moussa Arafat's body being taken from the house to Shifa Hospital in Gaza City, but angry bodyguards prevented him from taking pictures.
There was no immediate comment from the Palestinian Authority, but a spokesman said a statement would be issued later Wednesday, reports the AP.
