An Israeli drone attack on Wednesday targeted a vehicle in Wadi al-Hujair, about a mile from the border between Israel and Lebanon.
"The Israeli military will take action against all attempts by Hezbollah to rebuild or establish a military presence under civilian cover," Israel said in a statement.
In another raid on Hanin, also near the border, "one person was killed and one injured" according to Lebanon's Health Department.
According to the UN Human Rights Office, over 70 civilians have been killed in operations by the Israeli military since the ceasefire in Lebanon came into effect on November 27.
A representative of the Hezbollah movement, MP Hassan Fadlallah, said that over 180 people have been killed since the ceasefire was signed – but Fadlallah did not specify how many of these were members of Hezbollah.
