RISHON LETZION, Israel ? A suicide bomber blew himself up in a southern city Wednesday night, killing two other people and wounding 27, police and rescue workers said. The suicide blast, the second here in two weeks, followed a series of Israeli attacks that left five Palestinians dead.

Among the Palestinians killed in the attacks was Mahmoud Titi, 30, local leader of the Al Aqsa Martyrs Brigade militia who had said his goal was to build a Palestinian army that would hunt and kill Israeli soldiers and settlers.

In Rishon Letzion, a residential community of 100,000, police spokesman Gil Kleiman said two people and a suicide bomber were killed and 27 wounded, including three in critical condition.

Israel television said the dead were a 15-year-old boy and a 66-year-old man.

The bomber blew himself up under a green canopy at the edge of a small park where immigrants from the former Soviet Union gathered nightly to play cards.

Police spokesman Haim Cohen said the bomber had dyed his hair blond, apparently so that the Russians would not think he was an Arab.

“His hair was dyed blonde, short, punk looking,” Cohen said. “I’m sure he disguised himself so as not to arouse suspicion at the scene.”

There was no immediate claim of responsibility.

“There was a loud boom and I just saw body parts,” said witness Orin Mahmon. “I saw a guy all black and people with no arms and legs.”

After the bombing, a body lay under the canopy, covered with a black blanket. Blood was splattered across the pavement and a blood stained red scarf laid on the pavement.

One woman stood at the corner of the park crying because she could not find her son.

On May 7, a suicide bomber blew himself up at a pool hall in the same city, 10 miles south of Tel Aviv, killing 15 Israelis and himself.

Following Wednesday’s blast, police closed off the area and ambulances raced to the scene. The bomb went off at 9:09 p.m. on Rothschild Street on a pedestrian mall in the middle of the city.

David Baker, an official in the Israeli Prime Minister’s Office, said the bombing, “was another cowardly act of terror committed by Palestinian terrorists who have once again resorted to their murderous deeds. Israel will not buckle under in the face of terror and we will use whatever measures are needed to root it out.”

The last bomb attack in Israel was in the coastal city of Netanya on Sunday, killing three people plus the Palestinian bomber and wounding dozens.

On Monday, a suicide bomber detonated explosives at a northern Israeli junction, killing only himself.

An attack on March 27 that killed 28 people set off a massive Israeli military operation in the West Bank, aimed at rooting out “terrorist infrastructure.” During the operation, which wound-down this month, Israel took control of main towns and refugee camps and fought battles with Palestinian gunmen and bombers.

Yasser Arafat is under pressure to rein in militants and end the terror that has taken the lives of scores of Israelis over the last 19 months. The Palestinian leader condemned the May 7 attack and called on his security forces to halt attacks against Israeli civilians.

Since Israeli-Palestinian violence erupted in September 2000, there have been nearly 60 suicide bombings.

Earlier Wednesday at the Balata refugee camp next to Nablus, witnesses said Israeli forces fired shells at the camp cemetery, killing three activists, including Titi and a bystander.

In a statement, the military described Titi as a “senior terrorist” responsible for many attacks against Israelis. The statement said that after the attack, Israeli forces left Palestinian territory.

In a March 8 interview, Titi told The Associated Press that his goal was to build a Palestinian army that would hunt and kill Israeli soldiers and settlers. Until then, he said, his men were examining maps of Israel to pick out targets for attacks.

“Many of us know Israel very well and know the restaurants, cinemas and theaters,” Titi said in the interview.

Earlier, at the main checkpoint on the edge of Bethlehem, Moussa Daraghmeh, 35, was shot dead during a confrontation with Israel border police.

The army said Daraghmeh was among a group of Palestinians seeking to illegally enter nearby Jerusalem.

Another Palestinian man died when explosives he had went off prematurely as he walked toward a road junction outside the West Bank town of Jenin, the military said.

In a pre-dawn raid in Salfit in the West Bank, soldiers destroyed an explosives workshop, confiscated weapons and arrested “about 15 Palestinians suspected of involvement in terrorism,” a miltary statement said. The soldiers left Salfit before nightfall Wednesday.

The Israeli military also cut the Gaza Strip in two by blocking the main road in response to repeated attacks by Palestinians on Jewish settlements. The new measure created more hardships for 1.1 million Palestinians living in the narrow strip on the Mediterranean coast.
