Hizbullah operatives are their continuing attempts to carry out terror attacks or kidnap Israelis abroad, security experts told Israel Radio on Friday morning, apparently as revenge for the killing of terror chief Imad Mugniyeh, for which the group blames Israel. The sources said that while there had been no exceptional incidents recently, there was nothing that could be done to prevent such incidents. "We're not taking any chances on the matter. Hizbullah will try to carry out terror attacks at any opportunity," the security experts said. On Thursday night, Channel 10 reported that several Israeli businessmen in Israel received warning of terrorist threat from the Counter-Terrorism Bureau, and were flown back home.
