Bus blast in Bulgaria organized by Hezbollah

Israel was quick to blame Iran and its Lebanese ally Hezbollah for the attack and a U.S. official told The Associated Press on Thursday night that Hezbollah was believed to be behind the attack. The official spoke on condition of anonymity because it was a sensitive intelligence issue.

The victims included the Bulgarian bus driver and five Israelis, including a pregnant woman.

He looked like any other impatient tourist checking the big board at airport arrivals: a lanky, long-haired man in a baseball cap with his hands in the pockets of his plaid Bermuda shorts, a bulky backpack hanging from his shoulders, the Huffington Post reports.

Minutes later, authorities say, the man, filmed by security cameras at the Burgas airport, would board a bus filled with young Israeli tourists and blow himself up, killing six others as well.
