Israel’s military warned Lebanese civilians Monday not to return to dozens of villages in southern Lebanon, alleging Hezbollah activity there is violating a cease-fire reached last week.

Thousands of displaced residents have begun making their way back to parts of southern Lebanon since the truce between Israel and Lebanon took effect Friday.

Since the cease-fire began, Lebanon's armed forces have reopened a key road linking the southern city of Nabatiyeh with the Khardali area after it was closed due to Israeli strikes.

They have also partially restored access to the Burj Rahal-Tyre bridge.

But the Israeli military Monday demanded that civilians avoid returning to numerous villages in the south.
