"A short while ago, the IAF (air force) struck a Hezbollah terrorist who was engaged in re-establishing terrorist infrastructure and directing Hezbollah terror activities in southern Lebanon," the military said in a statement.

"The IDF will continue to operate to remove any threat to the State of Israel and will prevent any attempt by Hezbollah to rebuild itself."

Lebanon's official National News Agency reported one killed and one wounded in an "Israeli drone strike" on a car in the southern village of Kherbet Selm, citing the health ministry.

On Friday, the Israeli military said it had conducted "intelligence-based strikes" on Hezbollah military sites in southern Lebanon, "in which weapons and rocket launchers belonging to Hezbollah were identified".

It said the weapons "posed a threat to the State of Israel and constituted a blatant violation of the understandings between Israel and Lebanon".

A November 27 truce largely halted more than a year of hostilities between Hezbollah and Israel, including two months of full-blown war in which Israel sent in ground troops.

Israel has continued to carry out periodic strikes on Lebanese territory since the agreement took effect.

Israel had been due to withdraw from Lebanon by February 18 after missing a January deadline, but it has kept troops at five locations it deems "strategic".

The ceasefire also required Hezbollah to pull back north of the Litani River, about 30 kilometres (20 miles) from the border, and to dismantle any remaining military infrastructure in the south.
