Hezbollah has replaced a top security official who was in charge of coordination with Lebanon's security agencies after he told the group's leadership that he wants to step down, two officials with the group who were not authorized to speak publicly on the matter said.

Wafiq Safa had headed Hezbollah's Liaison and Coordination Unit for decades and it was not immediately clear what his new job within the Iran-backed group is going to be. Hezbollah's leadership accepted Safa's resignation Friday, one of the officials said.
