The bus bombing that killed at least eight people at a Bulgarian airport yesterday, most of them Israelis, was probably the work of a suicide bomber, according to Bulgarian authorities. Investigators believe that the man—who was filmed by security cameras walking around the airport for an hour before the attack—detonated a bomb soon after boarding the bus. The suspected attacker was carrying an American passport and a Michigan driver's license, but the FBI determined that the documents were fake, according to the Jerusalem Post.
The Israelis had just arrived on a flight from Tel Aviv and were on their way to a beach resort. At least 30 of them were injured in the attack. Israeli Prime Minister Benjamin Netanyahu said all signs point to the involvement of Iran, which he noted was also behind recent attempted attacks on Israelis in Thailand, India, and Georgia, CNN reports. "This is a global Iranian terror onslaught, and Israel will react firmly to it," he vowed. Iranian state media dismissed Netanyahu's accusations as "ridiculous" and "sensational," describing the charges as an attempt to discredit Iran and its ally Syria, AP reports.
