A Lebanese source familiar with the decision said the funding included US$190 million for the Lebanese armed forces and US$40 million for the internal security forces.

Democratic US congressional aides said the funds had been released just before Washington’s fiscal year ended on Sept 30.

“For a small country like Lebanon, that’s really, really significant,” one of the aides said on a call with reporters, requesting anonymity in order to speak freely.

The funding was released at a time when the Republican president’s administration has been slashing many foreign assistance programmes, saying that its priority in spending taxpayer dollars is America First.

The release of the funds appeared to reflect the priority Trump has put on trying to resolve the conflict in Gaza and the wider region.

Asked for comment, a state department spokesperson said in an emailed statement that US assistance supports Lebanese forces “as they work to assert Lebanese sovereignty across the country and fully implement UN Security Council Resolution 1701, the only viable framework for a durable security arrangement for both Lebanese and Israelis.”

The resolution, adopted in August 2006, ended the last round of deadly conflict between Hezbollah and Israel.

A conflict between Israel and Lebanon that began a year ago has battered Hezbollah and left swathes of Lebanon in ruins.

President Joseph Aoun and prime minister Nawaf Salam asked the US-backed army on Aug 5 to devise a plan to ensure that all arms across the country would be in the hands of security forces by the end of the year.

Hezbollah has rejected calls to disarm since the devastating war with Israel. But the Iran-backed group is under pressure to give up its weapons from its rivals in Lebanon and from Washington.

The Lebanese source said the funding would allow the internal security forces to take over internal security in Lebanon so the LAF can focus on other critical missions.
