GAZA - Israel killed 15 Palestinians, nearly all of them militants, in the Gaza Strip on Tuesday, dealing its deadliest blow to Hamas in more than a year in raids that followed a peace mission by U.S. President George W. Bush.
A volunteer from Ecuador, working on an Israeli kibbutz, or farming community, bordering the Hamas-controlled Gaza Strip, was killed by a Palestinian sniper near the frontier fence. Hamas claimed responsibility for shooting the man.
The violence, four days after Bush ended a visit to Israel and the occupied West Bank, resulted in the highest number of Palestinians killed in a single day since late 2006. Israel said it mounted the operation to curb rocket attacks from Gaza.
Local medical workers and Hamas said 15 Palestinians - 12 Hamas men, one other militant and two civilians - were killed in fighting with Israeli forces in the northern part of the territory and east of Gaza City.
"There was a massacre today against our people, and we say to the world that our people will not remain silent against such crimes," Palestinian President Mahmoud Abbas told reporters in the West Bank city of Ramallah.
But Abbas, whose Fatah faction lost control of the Gaza Strip in June to Hamas Islamists, said that with "a will and a desire for peace" on the part of Israel and the Palestinians, an agreement was possible this year.
Israeli President Shimon Peres said as long as Gaza militants continue to fire rockets into the Jewish state, "we are left without a choice but to answer and stop it".
Hamas Islamists oppose U.S.-encouraged peace talks between Israel and the Palestinian Authority. Bush predicted during his three-day visit that a peace treaty would be signed before he left office in January 2009, despite deep public scepticism.
