A second terrorist bombing in London and the possible targeting of Israeli offices in the U.S. put authorities on a state of red alert. In the British capital, five people were injured this morning in a blast outside a Jewish fund-raising group's headquarters -- the city's second car-bombing in 12 hours. Fearful that the recent bombings in Britain, Argentina and Panama could lead to a wave of terrorism aimed at halting the Middle East peace process, Israel demanded tighter security worldwide. Nine U.S. cities responded promptly. In New York City, for example, police surrounded the Israeli consulate with 10 garbage trucks to prevent would-be car bombers from getting too close to the facility. The FBI said "reliable" sources have tagged the consulate and Israel's U.S. embassy in Washington as potential terrorist targets within the next 48 hours.
