An Israeli air strike has killed two Palestinian militants in the Gaza Strip.
The men, who were brothers, belonged to the Army of Islam - a radical group which Israel says is affiliated with al-Qaeda.
Israel said one of the men had been involved in a plot to kidnap its citizens in the Sinai Peninsula in Egypt.
It is the second time this month that Israel has targeted the group.
The Israeli army said the two men were killed when their car was stuck by a missile in Gaza City.
It said the elder of the two, Islam Yassin, was a senior figure in the Army of Islam who was personally involved in the kidnapping plot.
The BBC's Gaza correspondent Jon Donnison says the Army of Islam has often fired rockets into Israel.
It has been in conflict with Hamas - the Islamist group that controls Gaza - which it accuses of being too moderate.
Two weeks ago another of its senior members, Mohammad Namnam, was killed in an Israeli air strike.
Last week Israel's National Security Council warned Israelis visiting the Sinai peninsula to leave at once because of the danger they might be kidnapped by Islamist militants.
