The leader of Lebanon’s Hezbollah group has warned that if Israel’s attacks on Lebanon continue and the Lebanese state does not act to stop them, the group will eventually resort to other alternatives.

Israel said on Friday it had intercepted a projectile launched from Lebanon and vowed a strong response to protect its security - the latest strains to a shaky truce that ended a year-long war between Israel and Lebanese armed group Hezbollah.

Israel delayed a promised troop withdrawal in January and has continued to occupy several hilltops in south Lebanon. It has also carried out near-daily attacks on the country, claiming it was striking Hezbollah fighters and weapons.
