GAZA (Reuters) - Israeli forces killed four Palestinianboys playing football in the Hamas-run Gaza Strip on Thursday,medical workers said, during intensified attacks in response tothe death of an Israeli in a rocket strike.
The deaths of the boys, aged 10, 12, 13 and 15, near thetown of Jabalya, raised to 24 the number of Palestinians killedin the Gaza Strip over the past two days. An Israeli militaryspokeswoman had no immediate information about the incident.
"We are at the height of the battle," Israeli PrimeMinister Ehud Olmert said in Tokyo, where he met U.S. Secretaryof State Condoleezza Rice before her visit next week to Israeland the occupied West Bank to try to push along peace talks.
But Olmert appeared to suggest a major Israeli groundoperation against militants in the Gaza Strip was not imminent,saying Israel's fight against them was a "long process" and ithad "no magic formula" to halt frequent rocket attacks.
Twelve Palestinians -- the four boys, seven militants and acivilian -- were killed in air strikes or by missiles firedfrom the ground on Thursday, the medical workers said. A Hamasmilitant died of wounds suffered overnight.
The father of two of the youths wept in a Gaza hospital,unable to speak. Medical workers said the boys were playingsoccer when an Israeli missile struck.
A six-month old Palestinian baby was killed in an Israeliair strike on Wednesday. Hours earlier, five senior Hamas mendied in an attack from the air and a rocket fired by theIslamist group at the Israeli border town of Sderot killed anIsraeli civilian, the first such death since May.
The Israeli military said 21 rockets and 12 mortar bombswere fired from the Gaza Strip on Thursday. Three people werewounded and Israel's internal security minister, visitingSderot, scrambled for cover as a siren sounded.
Two rockets flew deep into southern Israel, hitting a houseand cemetery in Ashkelon, a city of 120,000 people. Police saidno one was hurt.
PEACE PROCESS
Nabil Abu Rdainah, a spokesman for Palestinian PresidentMahmoud Abbas, who is negotiating with Israel, said in astatement its military actions "meant only one thing: theIsraeli government ... aims to destroy the peace process".
Olmert said at the end of a four-day visit to Japan "thecontinuous shooting of Qassam rockets against uninvolved,innocent civilians is a major threat to the stability" ofIsrael's political contacts with Abbas's Palestinian Authority.
He said, however, that he planned to hold another of hisregular meetings with Abbas within the next two weeks.
Washington hopes the talks can result in a statehood dealthis year but Palestinians have complained about their slowpace and Olmert has said the goal of the negotiations was anunderstanding of "basic principles" rather than a full accord.
At a Gaza funeral attended by hundreds, the father ofsix-month-old Mohammed al-Burai cradled the baby's body in hisarms. It was wrapped in the green flag of Hamas. In Sderot,Israelis mourned 47-year-old Ronnie Yehiye, a father of four.
In Tokyo, Rice was asked whether she urged Olmert not touse disproportionate force in responding to the rockets.
"I think that's not a good way to address this issue. Theissue is that the attacks -- rocket attacks -- need to stop,"she told reporters.
Palestinian Foreign Minister Riyad al-Malki, speaking inEast Jerusalem, said: "These stupid missiles being launched --firecrackers, but at the end they have killed Israeli civilians-- we condemn this, clearly, openly, straightforwardly.
"But at the same time, we condemn all the Israeliincursions into Gaza, killing Palestinian civilians, destroyingtheir houses, preventing them from having a normal life," hesaid.
