Israel said it had targeted militants headed to a rocket facility, but neither Israel nor Hezbollah seemed keen to immediately return to full-scale fighting.

The bursts of violence — with no reports of serious casualties — reflected the uneasy nature of the ceasefire that otherwise appeared to hold Thursday.

Israel on Thursday carried out its first airstrike on Lebanon since a truce with Hezbollah announced this week, saying it targeted the militant group's activity at a rocket storage facility in southern Lebanon that breached the ceasefire.
