Prime Minister Ehud Olmert on Thursday night called for an increase in the severity of punishment on Israeli citizens involved in carrying out terror attacks. "If we need to demolish houses, we'll demolish houses, and if we need to revoke benefits, we'll do that," he said, speaking at the Israeli Democracy Institute's Caesarea conference in Eilat. Olmert added that he had instructed ministers to initiate necessary amendments to the law. "The terror attack that happened yesterday in Jerusalem was a type that we haven't experienced in the past," he continued. "It was a terror attack carried out on Israel from within Israel, by someone from the Israeli side of the barrier."
