"An enemy drone carried out an air strike on the town of Shaara... near the eastern Lebanon mountain range, killing two people and wounding two" others, said the state-run National News Agency.

Lebanese militant group Hezbollah and Israel fought a war last year that ended in a late November ceasefire, which has largely held despite mutual accusations of violations.

Hezbollah was left weakened by a year of hostilities, including the two months of all-out war, in which its leadership was decimated.

Under the November 27 truce agreement, Israeli forces were to withdraw from southern Lebanon while Hezbollah was to remove its military infrastructure from the area. Troops remain in five points deemed "strategic" by the Israeli military.
