A loud sound in Beirut probably was caused by Israeli warplanes flying over the Lebanese capital, according to a security source and a Reuters witness, and Reuters reports.
Israeli planes were flying low over Beirut at the time, the security source said. A Reuters witness reported two jets in the skies over the capital.
Earlier in the day, Israeli aerial defences were triggered and fighter jets scrambled after a radio-controlled aircraft crossed into Israel from Lebanon, Israel's military said. Lebanon's Hezbollah group said it had flown a drone over Israel on a reconnaissance mission for 40 minutes.
