The attacks follow weeks of growing tensions between both sides. On Tuesday, about 30 Israelis were injured when Hezbollah rocketed villages in northern Israel. Although it is not immediately clear how long Israel's operation will continue, Israeli Army Chief of Staff Gen. Amnon Shahak suggested Israel is prepared to carry out more assaults. Shahak added the attacks were not aimed at the Lebanese army and that Israel was solely targeting Hezbollah strongholds. Shahak said one Lebanese military vehicle fired at an Israeli aircraft, which fired back.
Reports suggest one Lebanese soldier was killed in the incident.
A journalist in Beirut told CNN the atmosphere in the Lebanese capital is chaotic. Fearing more attacks, Lebanese officials, he said, have told residents to stay away from Hezbollah areas. Meanwhile, Israel officials, anticipating Hezbollah retaliatory strikes, have ordered residents in northern Israel close to the Lebanese border to stay in bomb shelters. Children in those regions are being evacuated to central Israel for safety purposes. CNN Correspondent Jerrold Kessel contributed to this report.
