The attack was on a car travelling along a coastal road near a beach refugee camp in Gaza, witnesses said. One source identified the men as belonging to the Popular Resistance Committees, a network of militant groups that has been responsible for firing rockets into southern Israel in the past.
An Israeli military spokeswoman said she was checking the report. In earlier violence, four Palestinians were wounded by Israeli fire near the southern part of the Israel-Gaza border, medical officials said. They included a 11-year-old boy who was in serious condition. The Israeli army said its troops near the border fence had been targeted by an explosive device and tanks responded with "fire towards lookout posts used to guide the attack against the forces."
Palestinians from Gaza have launched several rocket attacks into Israeli territory in the past two weeks and Israel has retaliated by bombing targets in Gaza, including training
grounds belonging to militant factions.
