Palestinian militants in the Gaza Strip fired a mortar shell at the western Negev on Thursday morning, hours after a lull in fighting went into effect as part of an informal Egyptian-brokered truce.
Palestinians had launched dozens of rockets into Israel over the preceding two days and Israel conducted a number of air raids on the coastal enclave, raising fears of a prolonged, bloody confrontation between the two sides.
An Israeli military spokeswoman said the last known rocket was fired from Gaza on Wednesday at 8.00 p.m. An Israeli defense official said no formal agreement had been reached with Hamas, the Islamist faction which controls the Gaza Strip, although Egyptian defense officials had been instrumental in restoring calm.
"The Egyptians have a very impressive ability to articulate to [Hamas] that its primary interest is not to attack and use terror against Israel or other targets," Israeli defense official Amos Gilad told Israeli Army Radio.
But he added that there was no direct agreement with the Islamist faction which refuses to recognize Israel and calls for its destruction.
"It can be said categorically that there is no agreement with Hamas, there has never been and there will never be. ... The only thing that has been set and said is that there will be calm. We are not interested in an escalation," Gilad added.
On Wednesday, Israel killed a Hamas militant in an air strike which it said was intended to stop rocket launches. On Tuesday, Israel killed three Hamas men, saying they had either launched attacks or were about to do so.
