Lebanon’s Health Ministry said 10 people were killed and 37 others were wounded by a pair of strikes Tuesday evening in the southern coastal city of Sidon.
Within a few hours, a third apparent Israeli strike targeted another building in the same neighborhood, Lebanon's state-run media reported.
Another Israeli airstrike hit the nearby Sarafand town and killed eight people and wounded 21 others, according to the Health Ministry. It said rescue efforts were ongoing in the town, which is about 10 kilometers (6 miles) further south down the coast.
According to the National News Agency, the first strikes in Sidon targeted an area sheltering displaced people that was adjacent to a Hezbollah complex called Sayyed Shohada, located a few hundred meters (yards) from a Lebanese army barracks.
The intended target of the strikes was not clear and the Israeli army gave no warnings ahead of the bombing.
Earlier Tuesday, the Israeli military had issued evacuation orders for 16 villages in South Lebanon, instructing residents to move north of the Awali River.
