TULKAREM, West Bank – Israel released hundreds of Palestinian Arab prisoners yesterday, completing a pledge made under a cease-fire agreement, hours after Israel and the Palestinians announced their leaders would soon meet for the first time since February.

The prisoner release – the final part of an Israeli pledge to free 900 prisoners as part of the February 8 truce – and the summit could help the sides move toward coordinating Israel’s withdrawal from the Gaza Strip this summer. Pledges to coordinate the pullout have made little progress so far.

In neighboring Jordan, Palestinian leader Mahmoud Abbas was released from a hospital after undergoing a heart procedure. Mr. Abbas, who has a history of heart trouble, told reporters he felt “just fine.”

Doctors said Mr. Abbas underwent a coronary angiogram – a common procedure to ensure that the arteries are not clogged. Palestinian officials said Mr. Abbas’s June 21 summit with Israeli Prime Minister Sharon remained on schedule.

The 398 Palestinian Arab prisoners were released at different checkpoints yesterday in the West Bank and at the Erez crossing into Gaza, where they were warmly welcomed by joyous relatives.

In Tulkarem, the prisoners flashed victory signs, praised God, and kissed the ground as they got off Israeli buses. The men boarded Palestinian buses, which took them about 100 yards to their cheering relatives. Young girls threw candy as the prisoners were reunited with family members.

Prisoners herded into cars at the Erez crossing were cheered by crowds as drivers honked and waved Palestinian flags out of windows.

Sami Abu Nahal, 42, from the Beach refugee camp in Gaza, said he was looking forward to meeting his 4-year-old daughter for the first time, but still had mixed feelings about his release.

“I can smell the freedom. I am happy to see my daughter, Wala,” said Abu Nahal, who spent four years in prison. “But at the same time, I’m feeling sad because I left friends and brothers inside the Israeli jails.”

In the West Bank town of Nablus, known as a stronghold of Palestinian Arab militants, thousands of people celebrated the release, including dozens of masked men who fired guns into the air. Some 85 of the prisoners freed Thursday were from the Nablus area.

At the Tarkumiya checkpoint near the West Bank city of Hebron, a replica of Jerusalem’s Dome of the Rock mosque greeted the prisoners.

The fate of the prisoners held by Israel is extremely emotional for Palestinians, and Mr. Abbas has attempted to make their release a priority. With an estimated 8,000 Palestinian Arabs in Israeli prisons, most Palestinian families have friends or relatives behind bars.

The Palestinians want Israel to release all of the prisoners, while Israel refuses to free anyone involved in attacks on Israelis. The Palestinians have also complained that in the past Israel only freed prisoners who had committed minor infractions and were near the end of their sentences.

For the first time, Israel released nearly 90 prisoners who had only served a fraction of their sentences, with the hope of propping up Mr. Abbas’s fragile government.

Some of the prisoners released yesterday had been charged with attempted shootings, preparing explosives, and assisting attempted murder, but most were sitting in prison for nonviolent offenses.

A senior Palestinian official, Saeb Erekat, welcomed yesterday’s release, but said Israel must go further.

“I think it’s making 400 Palestinian families happy today and I hope that we can also make happy the other 8,000 families who are concerned about their loved ones,” Mr. Erekat said.

Mr. Sharon agreed at a February summit with Abbas in Egypt to release 900 prisoners. Shortly after the summit, the first 500 were freed. Yesterday’s release completed the pledge.

Israel also agreed under the truce to turn over five West Bank towns to Palestinian security control. But so far, it has only turned over two of the towns, accusing Palestinian forces of failing to act against militants in areas under their control.

Also yesterday, Israel and the Palestinians said their leaders would meet on June 21. Mr. Abbas, also known as Abu Mazen, and Mr. Sharon will discuss the release of more prisoners at the upcoming summit, Mr. Erekat said.
