JERUSALEM - Eleven percent of those involved in terror attacks are Palestinians who entered Israel via the Family Reunification Law, Shin Bet Chief Yuval Diskin said on Tuesday. The reunification law allows Palestinians to reunite with their Israeli spouses in Israel. Diskin made the comments to the Knesset Interior Affairs committee, which is examining ways to balance the reunification law with security concerns. Diskin also said that 97 percent of Palestinians involved in terror attacks are men aged 16-36, and women up to the age of 25. Under a proposed amendment to the reunification law, men below 35 and women below 25 will therefore not be able to enter the Green Line under the law. The amendment is, according to Diskin, a result of security concerns alone. “A blue (Israeli) identification card and yellow (Israeli) license plate double the ability of terrorists to camaflouge themselves and strike at attractive targets, and to infiltrate into Israel, as well as smuggle weapons and explosives, carry out logisitical operations, and set up terror infrastructure," he said. "The reunification law give terror operators more room to act,” said Diskin. Law costing lives Since the start of the intifada, 16 approved cases under the Family Reunification Law have been connected to suicide bombings in one way or another, resulting in the murder of 19 people. The government’s legal adviser, Menachem Mazuz, also emphasized that the proposed limitations on the reunification law are motivated by security fears alone, and not by demographic concerns. “During the committee (discussions,) there were claims that the amendments were due to the demographic implications of the law, but the amendments are there exclusively because of security problems," he said. "The amendment was initiated by security soruces and its implications are in the security sphere,” Mazuz said. “The involvement of family reunification cases in terror attacks is ten times greater than the involvement of Israeli Arabs in attacks,” he added. Outbursts of Terror Since 2000, there have been 25,375 terror attacks and attempted attacks, in which 1,148 Israelis have been killed, the Shin Bet chief said. Despite a certain calming down period of late, said Diskin, there is no significant change in plans by terror organizations to carry out attacks. “The security situation has not changed, even if there was a lowering of attacks lately,” he said. “At this point there is actually a rise in the number of terror attacks and scope of warnings.” “In the last five years, many Israeli citizens have paid with their lives. This situations has not changed, and uncertainty is still high," Diskin said.
