Israel has intensified its hostile military actions against targets on Syrian territory, with more than 127 attacks in almost a year, resulting in at least 100 deaths and extensive material damage.
At least 24 people, mostly children, were killed in an Israeli bombing of a building in the village of Alamat in southern Lebanon on Sunday.
The Lebanese Health Ministry said eight other people were injured as efforts continued to clear the rubble and search for the missing.
