BEIRUT/JERUSALEM — Israel threatened on Tuesday to return to war in Lebanon if its truce with Hezbollah collapses, and said this time its attacks would go deeper and target the Lebanese state itself, after the deadliest day since the ceasefire was agreed last week.

In its strongest threat since the truce was agreed to end 14 months of war with Hezbollah, Israel said it would hold Lebanon responsible for failing to disarm militants who violated the truce.

“If we return to war we will act strongly, we will go deeper, and the most important thing they need to know: that there will be no longer be an exemption for the state of Lebanon,” Defense Minister Israel Katz said.

“If until now we separated the state of Lebanon from Hezbollah… it will no longer be [like this],” he said during a visit to the northern border area.

Despite last week’s truce, Israeli forces have continued strikes in southern Lebanon against what they say are Hezbollah fighters ignoring the agreement to halt attacks and withdraw beyond the Litani River, about 30 km (18 miles) from the frontier.

On Monday, Hezbollah shelled an Israeli military post, while Lebanese authorities said at least 12 people were killed in Israeli airstrikes on Lebanon.

Katz called the Hezbollah attack “the first test” and described Israel’s strikes as a strong response.

The Beirut government must “authorize the Lebanese army to enforce their part, to keep Hezbollah away beyond the Litani, and to dismantle all the infrastructure,” Katz said.

“If they don’t do it and this whole agreement collapses then the reality will be very clear.”
