Palestinian medical sources say an Israeli air strike has killed a senior security official in the Hamas-led Palestinian government.
The sources say Jamal Abu Samhadana was among four people killed in Thursday's attack on a training camp in Rafah in the southern Gaza Strip. The Israeli military confirmed the air strike, saying the training camp was the target, not anyone specific.
Abu Samhadana was a leader of a Palestinian militant group called the Popular Resistance Committees.
He was wanted by Israel for rocket attacks into Israeli territory. He was also a suspect in the 2003 bombing of a U.S. diplomatic convoy in the Gaza Strip. Three people died in that incident.
His appointment in April to a senior position in Hamas' interior ministry angered Israel and Palestinian President Mahmoud Abbas, whose Fatah movement rivals Hamas.
Meanwhile, an aide to Mahmoud Abbas says the Palestinian president will announce Saturday a referendum on his controversial statehood plan that recognizes Israel. The aide says Mr. Abbas will likely set July 31st as the date for the referendum.
The Hamas-led government has refused to accept Mr. Abbas' plan, which calls for a two-state solution with Israel.
Hamas does not recognize Israel. The charter of the Islamic militant group calls for Israel's destruction.
