At least nine people are dead and 11 others injured in Israeli strikes on two towns in southern Lebanon, the Lebanese Ministry of Health said Saturday.
Seven were killed and two others wounded in a strike in the town of Ansar, the ministry said. Three children and 2 women were among the dead according to authorities.
Another Israeli strike left two dead and nine injured in the town in Der al-Zahrani, the health ministry said.
In a statement, the Israel Defense Force said the strikes on "terror infrastructure" were in response to action against its soldiers by Hezbollah.
"The IDF will not allow the Hezbollah terrorist organization to harm Israeli civilians and IDF soldiers, and will continue to operate to remove threats," the IDF statement said.
Lebanon Prime Minister Nawaf Salam said the escalation "undermines efforts to stabilize the situation in the south."
"The seven martyrs of the Israeli airstrike on the town of Ansar are not 'military infrastructure,' nor are the children and women killed in it military targets," Salam said.
Israel and Lebanon have been in talks since signing a "framework agreement" in June.
Despite the truce, the Israeli military has continued to strike Hezbollah targets and remains present in southern Lebanon.
Lebanon's president Joseph Aoun condemned Saturday's attacks, calling them violations and "a clear message to the negotiation track and to the American efforts aimed at implementing this agreement," the Lebanese president's office said in a statement.
Israel has vowed to remain in southern Lebanon until Hezbollah is disarmed.
