The health ministry said "the raid carried out by the Israeli enemy on the locality of Aitaroun left one dead", a day after Israeli strikes in the same region killed two people.

The Israeli military said earlier that it had struck "Hezbollah terrorist infrastructure sites" in southern Lebanon overnight, without offering details.

The military added that it would "operate against any attempts by Hezbollah to rebuild or establish a military presence under the guise of civilian cover".

Despite a November 27 ceasefire that sought to halt more than a year of hostilities between Israel and Hezbollah, Israel has continued to carry out near-daily strikes in Lebanon.

Hezbollah, significantly weakened by the war, insists it is adhering to the ceasefire, even as Israeli attacks persist.

Rocket fire from Lebanon into Israel has also been reported since the truce was struck, although no group has claimed responsibility for the launches.

On Wednesday, the Lebanese army said it had arrested several people suspected of firing rockets at Israel from Lebanon.

A security official told AFP that three of those detained were members of Hezbollah's Palestinian ally Hamas.
