Pompeo in Lebanon warns of Hezbollah's 'destabilising influence'

Top US diplomat Mike Pompeo warned on Friday of Shiite militant group Hezbollah's "destabilising activities" as he visited Lebanon on the latest leg of a regional tour to build a united front against Iran.

He flew in from Israel a day after he became the first high-ranking American official to visit the Western Wall in annexed east Jerusalem with an Israeli prime minister.

His visit also comes just hours after US President Donald Trump said Washington should recognise Israel's annexation of the Golan Heights, breaking with the policy of successive administrations as well as UN Security Council resolutions.

In a meeting with parliament speaker Nabih Berri, who is himself a Shiite, Pompeo warned of the "destabilising activities" of Hezbollah, an Iran-backed group that is targeted by US sanctions but holds cabinet posts in Lebanon.

"He highlighted US concerns about Hezbollah's destabilising activities in Lebanon and the region and the risks posed to Lebanon's security, stability and prosperity," US deputy spokesman Robert Palladino said.

Hezbollah has backed government forces in neighbouring Syria in the civil war that broke out in 2011.

Pompeo and Berri also discussed "the need to maintain calm along the boundary between Lebanon and Israel", Palladino said.

Lebanon and its southern neighbour are still technically at war, even after Israeli troops withdrew from the south of the country in 2000.

Israel and Hezbollah fought a devastating month-long war in 2006, and skirmishes still erupt along a UN-patrolled demarcation line.

The secretary of state then met Prime Minister Saad Hariri to discuss "the latest developments in Lebanon and the region", according to the premier's office.

Earlier, he met the country's first female interior minister.

"Pompeo met in Beirut today with Lebanese Minister of the Interior Raya al-Hassan," Palladino said.

They "discussed the regional and internal security challenges facing Lebanon and how the United States can help support the interior ministry's efforts to maintain safety and stability inside Lebanon."
