At least 10 people, including two children, were killed and five wounded in an Israeli air strike on a residential building in the southern Lebanese city of Nabatia, the state-run NNA news agency reported on Saturday.
The dead were all Syrian nationals, the NNA said, adding that a final number would be announced after DNA tests were conducted to determine the identities of those killed.
The Israeli military said that the airstrike targeted an arms depot used by Hezbollah militants.
The Israeli attack came after ceasefire talks between the Palestinian Islamist group Hamas and Israel were suspended on Friday with negotiators due to resume next week in Doha.
Also on Saturday, an Israeli drone targeted a motorcycle in the Kadmos area east of Tayr in southern Lebanon, injuring one person. A security source said that one person was killed in the motorcycle attack.
Tensions have risen in the region in recent weeks after 12 children and teenagers were killed in a rocket attack on Hezbollah in the Israeli-occupied Golan Heights. Israel retaliated by killing a top Hezbollah commander on the outskirts of Beirut.
