An Israeli warplane has bombed a Gaza metalworks factory.
The Israelis claim the site was used to manufacture weapons for Islamic Hamas. No one was hurt.
The factory was at the entrance to the Mughazi refugee camp.
Witness Mr Hassan Jabber, says several Israeli F-16 warplanes circled over the area, and then one of them dropped a bomb on the factory, causing a huge explosion.
Palestinian police and ambulances raced to the scene.
Palestinians said there were no casualties, but considerable damage was caused.
In a statement, the Israeli military said the factory was used to manufacture mortar bombs and rockets for Hamas.
"Because of the increase in firing mortars in recent days, the factory was bombed as part of the war against terrorist infrastructure," the statement said.
Palestinians said the bombed factory was one of the largest metal works facilities in the Gaza Strip and is owned by businessman Mr Omar Namruti.
