Four Palestinians were injured when Israeli troops opened artillery fire in the direction of a refugee camp in the central part of the Gaza Strip, Al-Quds radio reported on Friday.
At least three artillery shells exploded near Al Bureij camp on Thursday. Israeli military said the shells were fired at a group of Palestinian militants who attempted to blow up Israeli border defense installations.
After a 2009 military operation in Gaza, Israel has set up the so-called "buffer zone" along the border with the Gaza Strip that extends 150-300 meters into the territory of the enclave. Israeli army opens fire without warning at anyone who approaches the zone.
The Gaza Strip has been subject to Israeli attacks and economic blockade since the radical Islamic group Hamas took control of the enclave in the summer of 2007, ousting President Mahmoud Abbas's Fatah movement.
Israeli Operation Cast Lead, which lasted for three weeks and ended in mid-January 2009, killed some 1,300 Palestinians in Gaza and injured over 5,300 others. Up to 50,000 people were also left homeless in the enclave of 1.5 million.
