'The IDF is currently striking terrorist headquarters in the Dahiyeh district of Beirut in response to Hezbollah's fire toward Israeli territory,' the statement said.

'As long as the occupation exists, the resistance will continue,' Qassem warned.

'I was a little bit perturbed at his constantly fighting with Lebanon,' Trump said.

'No terrorist has immunity,' the statement said. 'Israel’s long arm will reach any enemy and any murderer.'

'There is concern that terrorist elements will seek to target a large-scale event,' the letter noted.

Trump expressed hope that Prime Minister Benjamin Netanyahu and Lebanese President Joseph Aoun will meet in Washington soon.

The announcement coincided with a new round of Israel-Lebanon talks in Washington aimed at reinforcing the ceasefire, even as violations continued on the ground.

The IDF described the incident as another blatant violation of the ceasefire.

The U.S. Embassy warned that the security environment in Lebanon remains complex and can change quickly.

'Hezbollah chose to attack Israel in the service of its Iranian masters and will pay the full price,' Katz said.

'They are Courageous, Bold, Loyal, and Smart. Israel fights hard, and knows how to WIN!'

In the hours leading up to the truce, Hezbollah launched heavy barrages toward communities in northern Israel.

Aoun spoke with Rubio and made clear he would not engage in a direct conversation with Netanyahu.

In recent weeks, Italy has voiced growing criticism of Israeli operations in Lebanon.

The US and the rest of the international community were wrong to assume that Hezbollah would honor the ceasefire agreement with Israel.

Netanyahu has recently informed ministers that Donald Trump has given Israel a green light to carry out a major military campaign against Hezbollah.
