Israeli strikes on southern Lebanon killed at least 15 people on Friday, state ​news agency NNA said, while Israel said the attacks ‌launched overnight were aimed at what it described as Hezbollah targets in several areas.

Residents and domestic media said Israeli airstrikes and ​shelling hit several towns in the Nabatieh district ​overnight and into early Friday, in a bombardment that ⁠NNA said was among the heaviest in recent weeks.

The ​Israeli military said it had struck what it described ​as Hezbollah militants and infrastructure at several southern sites, in response to repeated violations of the ceasefire by the Iran-backed group.

The escalation comes ​a day after Israel published a map showing an ​expanded military control zone in southern Lebanon beyond which it said ‌it ⁠would not rule out attacks, raising questions over Wednesday’s US interim peace deal with Iran.

The agreement calls for an end to fighting on all fronts, including Lebanon, and for parties ​to respect Lebanon’s ​territorial integrity ⁠and sovereignty.

A senior Israeli official said Israel was engaged in “stubborn negotiations” with US President ​Donald Trump’s administration over keeping troops deployed 10 ​km inside southern Lebanon as it pursues Hezbollah.

Israel has rejected calls to withdraw its forces from southern Lebanon, where Hezbollah ⁠has ​kept up attacks on Israeli positions, ​some employing explosive drones that have killed and wounded troops this week.
