"The IDF has begun to strike Hezbollah infrastructure sites in the Bekaa valley and in additional areas across southern Lebanon," it said in a brief statement on social media.

Hezbollah leader Sheikh Naim Qassem on Monday rejected Lebanon's planned direct talks with Israel, calling them a "grave sin" that will destabilize Lebanon, as he vowed to end the Israeli occupation of south Lebanon.

Qassem said Hezbollah will not give up its arms and people will return to their lands, vowing that Israeli troops will not remain on "a single inch of our occupied land".
