 The attacks Tuesday add to concerns about a wider war breaking out between Israel and Hezbollah in Lebanon. Hezbollah said an Israeli strike yesterday in Syria killed one of its operatives. The Associated Press identified him as a former bodyguard of Hezbollah leader Hassan Nasrallah. In response, Hezbollah said it fired a barrage of rockets toward the Golan Heights, territory Israel controls since capturing it from Syria in 1967. Israeli authorities say a married couple, a man and woman, were killed when the rocket hit their car.
