Kerry vows no reprieve for Arafat

Hospital sources said one Pale-stinian was killed and three others were wounded in an Israeli air strike on a house in the northern Gaza refugee camp of Jabaliya, the focus of a punishing Israeli military offensive launched 12 days ago.

They said the house was completely destroyed but could not identify the victims.

A Palestinian wounded in an Israeli air raid on October 1 in Jabaliya also died of his injuries on Sunday, hospital sources said. They named the victim as Raed al-Mabha, 22.

Sunday's deaths brought to 107 the number of Palestinians killed during Israel's "Days of Penitence" operation launched on September 28 that is aimed at halting militant rocket attacks from Gaza on Israeli soil.

Since the start of the Intifada or Palestinian uprising against Israeli occupation in September 2000, a total of 4,471 people have been killed, including 3,443 Palestinians and 954 Israelis.

Six Palestinians were also injured, three of them critically, when Israeli attack helicopters carried out two air raids in Jabaliya late Saturday, according to Palestinian medical sources.

The Gaza offensive has triggered international concern but an Arab-backed UN Security Council resolution calling on Israel to withdraw its forces was vetoed this week by its top ally, the United States.
