Israeli Prime Minister Benjamin Netanyahu on Monday expressed regret over the deaths of 16 Egyptian guards in an attack on Sunday by gunmen on the border with Israel, his office said in a statement.

It said that he was speaking during a visit with Defense Minister Ehud Barak to the site where five attackers crashed across the frontier in an armored vehicle into the Jewish state, where they were killed by Israeli forces.

Israel has improved the accuracy of its Arrow 2 missile interceptor system, including its ability to intercept medium-range missiles present in the arsenals of Iran and Syria, media reported on Monday.

The new system, known as "Block 4," will be installed in missile batteries in the coming weeks, reports said.

Five gunmen who slew 16 Egyptian guards near the border with Israel before crossing into the Jewish state in an armored vehicle have been killed, an army spokesman said Monday.

"The bodies of the five gunmen have been found by the Israeli army," said the spokesman a day after the incident but did not give details.

A key meeting of Non-Aligned Movement ministers which was to have taken place in the West Bank on Sunday was cancelled after Israel denied several of them entry, officials said.

The ministers were to have attended a two-day meeting of the movement's Palestine Committee in Ramallah at which they were poised to sign a declaration in support of a fresh Palestinian bid for upgraded U.N. membership.

Israeli soldiers shot and wounded a Syrian man trying to breach a frontier fence in the southern Golan with a pair of wire cutters on Saturday, a military spokeswoman said.

Lieutenant Colonel Avital Leibovich said Israeli forces "identified a civilian from Syria, a man approaching the border fence. The man was holding hydraulic cutters and tried to cut the fence.

President Michel Suleiman stressed on Saturday that the tripartite formula of the people, army and the resistance requires some clarification, noting that the goal behind the defense strategy is to “confronting Israeli aggression against Lebanese territories.”

“We have already stressed several times in ministerial statements the importance of the cooperation among the people, the army and the resistance but we need to clarify the means of cooperation,” Suleiman said from his summer residence in Beiteddine.

Israel on Thursday urged its citizens traveling in Egypt's Sinai peninsula to return immediately amid warnings of an attack.

The travel warning was based on information alleging militant groups from the Gaza Strip are operating in the area and plan to attack or kidnap Israeli tourists.

More than two weeks since a deadly bombing on a bus carrying Israeli tourists in Bulgaria, investigators have still not identified the young perpetrator or his suspected accomplices.

Police have the fingerprints and DNA of the bomber, who killed five Israelis and the Bulgarian bus driver as well as himself in the July 18 attack at Burgas airport, but they have drawn a blank on international databases.

Interpol has distributed a computer-generated image of the suspected suicide bomber who killed six people in an attack in Bulgaria last month.

The global policing body said Thursday it had issued a Black Notice -- used to seek information on unidentified corpses -- to its 190 member countries urging them to make the image public in the hopes of identifying the suspect.

The Israeli Defense Ministry estimated that if the country engaged in a war with Hizbullah and Iran some 200 Israeli civilians would die.

According to Israeli newspaper Haaretz, the number of fatalities could rise to 300 if Syria joins the war as well.
