The Israeli military says its naval force fired at a Palestinian boat off the central Gaza Strip today, killing four militants.
An Israeli military spokesman said a navy force "identified a squad of terrorists wearing diving suits on their way to execute a terror attack."
The spokesman said the force "fired and hit the terrorists."
Witnesses confirmed those killed were all wearing diving suits.
The al-Aqsa Martyrs' Brigade, the armed wing of President Mahmud Abbas' Fatah movement, said in a message sent to the media that the four killed were members of its marine unit and had been "on a training mission."
The message said more details would be available at a news conference later today.
