The Israeli military has carried out airstrikes in southern Lebanon, targeting what it says are Hezbollah infrastructures.

An Israeli air strike on a Palestinian refugee camp in southern Lebanon killed 13 people, the Lebanese health ministry said, an escalation that has heightened fears of a renewed Israeli offensive.

The Israeli military stepped up airstrikes in south Lebanon on Wednesday, killing at least one person as it pressed a campaign of near-daily attacks which it says is designed to block a military revival by Iran-backed Hezbollah in the border area.

State media and the Health Ministry in Lebanon say that an Israeli airstrike on a Palestinian refugee camp in southern Lebanon has killed 13 people and wounded others.

The Israeli army launched airstrikes in southern Lebanon on Wednesday, shortly after issuing evacuation orders despite a ceasefire agreement in place since last year. Military spokesman Avichay Adraee claimed on the US social media company X that the attacks targeted what he called Hezbollah military infrastructure in the south.

Tensions have been mounting in southern Lebanon for weeks, with the Israeli army intensifying near-daily air raids.

It was one of the deadliest Israeli strikes on Lebanon since a cease-fire with Hezbollah went into effect about a year ago.

Lebanon said at least 13 people were killed Tuesday in an Israeli strike on a Palestinian refugee camp in the country's south as Israel said it targeted a "Hamas training compound" operating in the area.
