Palestinian militants have again fired rockets into southern Israel, despite a massive Israeli Army offensive in Gaza aimed at stopping such attacks.

More than 60 Palestinians and several Israelis have been killed since the military operation began last Wednesday.

Palestinian militants fired two rockets into Sderot Monday, slightly wounding one person. The rocket attacks came as Israeli strikes in Gaza killed at least six Palestinians, including four militants. Other fighting killed at least two Palestinian civilians.

Meanwhile, Israeli troops and tanks pushed into Jabaliya refugee camp while others opened a new front in Khan Younis.

Israeli Prime Minister Ariel Sharon has vowed to stop militants from firing rockets into southern Israel. He said on Sunday Israel's offensive into the Gaza Strip will continue until the rocket attacks stop.
