Terrorism: Bomb on the bus A SUICIDE bomber with fake American documents blew up a bus in the Bulgarian holiday resort of Burgas on July 18th killing at least five Israeli tourists, the driver and himself, officials there said. Dozens were injured. Israel immediately blamed the Lebanese-based party-cum-militia Hizbullah and its Iranian backers. "Israel will respond forcefully to Iranian terror," said the prime minister, Binyamin Netanyahu. Bulgaria is a cheap and popular destination for Israeli youngsters and Israeli officials were already worried that it might be a terrorist target. The attack came on the anniversary of the bombing, also blamed on Hizbullah, of a Jewish community centre in Argentina in 1994, which killed 85 people. This year a car-bomb in New Delhi injured an Israeli diplomat's wife; another, in Tbilisi in Georgia, was detected in time. In Bangkok an Iranian man blew his legs off with a grenade while trying to flee after similar devices were found. Two Iranians arrested with explosives in Kenya in June confessed that they were seeking Israeli targets, among others, officials say. Magnetic car-bombs have killed several Iranian scientists linked to the nuclear programme there. Iran blames Israel for that.
