The suicide bomber who attacked last week turned out to be a British citizen. An accomplice, still being sought, was also British. As a result, British police rounded up other terrorist sympathizers. Palestinian terrorist organizations are encouraging foreign volunteers to come to Israel and participate in terrorist operations. Non-terrorist foreign volunteers are also coming to try and stop Israelis from destroying the homes of known terrorists. The volunteers get in the way of Israeli security operations and are sometimes injured or killed. Israel is starting to bar these volunteers and deport the ones that are already in the country.
