Two Palestinian militants died early on Thursday in an Israeli raid on the centre of the Gaza Strip, Palestinian medical officials said.
The fighters were members of the Al-Aqsa Martyrs Brigades, a group linked with the Fatah movement of Palestinian president Mahmud Abbas. They were killed near the town of Deir El Balah, the medics said.
A Brigades communique confirmed that two of its members had been killed.
An Israeli army spokesman questioned by AFP was unable to confirm the attack.
