WASHINGTON (AP) — The United States on Monday offered a $10 million reward for information on a Hezbollah operative who was convicted last year in the assassination of Lebanon’s former prime minister Rafik Hariri. The State Department said the reward will be given to anyone who provides information preventing Salim Jamil Ayyash from planning or engaging in any attack against a U.S. citizen or American interests. Ayyash is a senior member of Hezbollah's Unit 121, an assassination squad that the department said reports to Hezbollah leader Hassan Nasrallah
