Rescue workers used cranes, shovels and their bare hands in search operations that resumed early Friday in the rubble of a building that collapsed last month in Beirut’s catastrophic explosion, hoping to find a survivor after a pulsing signal was detected. A march and a vigil were planned Friday as well as a moment of silence at 6:08 p.m., the moment that marked the most destructive single incident in Lebanon’s history on Aug. 4. The search operation unfolding in Beirut’s historic Mar Mikhail district on a street once filled with crowded bars and restaurants has gripped the nation for the past 24 hours.
