Iran's parliamentary speaker, Mohammad Bagher Ghalibaf, will travel to Lebanon for the funeral of long-time Hezbollah chief Hassan Nasrallah on Sunday, Iranian media reports. Tens of thousands of people are expected to turn out in Beirut to farewell the Iran-backed terror group's leader. An Israeli airstrike killed Nasrallah on September 27 last year at the start of an all-out war between his group and Israel after roughly a year of lower-level conflict. The massive airstrike on Hezbollah's south Beirut stronghold also killed Abbas Nilforoushan, a senior commander in Iran's Quds Force -- the foreign operations arm of its Islamic Revolutionary Guard Corps. Hezbollah is part of Iran's 'Axis of Resistance,' a loose alliance of forces united in their dedication to destroying Israel.
