Jerusalem ? A suicide bomber blew himself up Tuesday in a Jerusalem fast-food stand, injuring seven people in the first attack in the city since back-to-back bombings prompted Israel to occupy major West Bank towns last month.

Earlier in the day, two Israeli settlers were shot and killed in the West Bank after they entered a Palestinian village, and a settler couple was seriously wounded after they were stabbed in their home by a Palestinian intruder.

Israeli officials warned that planned easing of restrictions in the seven Palestinian towns it occupied last month would be delayed if attacks continued. However, a spokesman for Prime Minister Ariel Sharon, Raanan Gissin, said Israel still wants to resume security talks with the Palestinians after a monthslong lull.

Also Tuesday, Israeli prosecutors charged two Palestinians with masterminding attacks that killed 17 Israelis, the first time indictments have been handed down in civilian court against alleged militants in the Palestinian uprising.

Thousands of Palestinians have been arrested since the September 2000 outbreak of violence. Palestinian prisoners’ organizations estimate that about 3,500 are still in custody.

In the Jerusalem attack, the bomber detonated his explosives inside the Yemenite Falafel Stand in one of the most heavily guarded areas of central Jerusalem and one of the most targeted by militants: There have been at least eight bombing and shooting attacks in the area in the past 22 months of fighting.

Seven people were injured in the attack, one of them moderately, police said.

Glass shards littered the street in front of the stand, which is popular with Jerusalem police, whose headquarters are nearby.

Israel Radio said it appeared the bomber drew the attention of police officers at the stand and that he set off the explosion prematurely.

Jerusalem Police Chief Micky Levy said the bomber was a 17-year-old from the West Bank town of Bethlehem, but did not give a name.

In the West Bank town of Ramallah, a Palestinian woman on her way to a suicide bombing was arrested by Israeli security forces, the military said. Ramallah is close to Jerusalem.

Separately Tuesday, the army said it had arrested a would-be suicide bomber found hiding in a house in the Israeli Arab village of Kfar Kassem. The army said the bomber showed soldiers an explosives-packed belt hidden in an olive grove, which soldiers later detonated.

The head of the Shin Bet security service, Avi Dichter, told a parliamentary committee Tuesday that Israel had received 60 warnings of pending attacks and had thwarted 12 in the past few days, a parliament spokeswoman said.
