Bulgarian officials have announced two members of the Lebanese group Hezbollah are suspected of involvement in a bus bombing that killed five Israeli tourists and a Bulgarian bus driver last July. Bulgaria’s interior minister said a “reasonable assumption” could be made the pair were members of Hezbollah’s militant wing. Hezbollah, however, has denied responsibility for the attack. In one of his first statements as secretary of state, John Kerry said the United States is acting “decisively and comprehensively” to curb Hezbollah’s impact and urged European governments to “take immediate action to crack down” on the group. Israeli Prime Minister Benjamin Netanyahu condemned what he called the “terrorist atrocity” of the bus bombing in Bulgaria.

Prime Minister Benjamin Netanyahu: “Six innocent people lost their lives there: five Israelis, one Bulgarian. It is a further corroboration of what we know, that Hezbollah and Iran are together building a worldwide terrorist network. They have attacked in a dozen countries. They’re planning attacks in dozens more. And it’s time that international community branded Hezbollah for the terrorist organization that they are.”
