The Israeli military said it had struck a number of military compounds belonging to the armed group Hezbollah.

Israel's ongoing military strikes in Lebanon send a "clear message" to Hezbollah, Defence Minister Israel Katz said on Tuesday, accusing the Iran-backed Islamist group of seeking to rebuild its forces in violation of a ceasefire agreement.

Twelve people, including five Hezbollah fighters, were killed and eight others wounded Tuesday in Israeli strikes on the Bekaa Valley in eastern Lebanon, security sources and the official news agency reported.
