By Maya Gebeily and Adam Makary BEIRUT (Reuters) -At least nine people were killed and three injured on Monday from Israeli strikes on two southern Lebanese towns, Talousa and Haris, as the Israeli military said it struck dozens of Hezbollah targets throughout Lebanon.

The IDF said it conducted a strike on military infrastructure sites near the border crossings between Lebanon and Syria, calling it a response to cease-fire violations.

The Israeli military said on Monday it struck dozens of targets throughout Lebanon, shortly after Hezbollah accused Israel of violating a ceasefire agreement and fired missiles on an Israeli military position in the disputed Shebaa Farms area.

Both sides have accused each other of violating the deal; Hezbollah fired into Israel for the first time since the truce took effect, and Israel responded with airstrikes.

Hezbollah has claimed the first strike against Israel since a US-backed cease-fire plan came into effect less than a week ago, prompting Israeli officials to vow a strong response in the most serious threat so far to the truce with Lebanon.
