US Secretary of State Mike Pompeo described Hezbollah as a risk to Middle East stability, Reuters reported.

Pompeo, who has been on a regional tour to promote the Trump administration's hard tack against Iran, received a warning from Israel which worries it may again be in the sights of Hezbollah forces winding down their intervention in Syria's war.

Meeting Israeli President Reuven Rivlin in Jerusalem, Pompeo listed Hezbollah, Palestinian Hamas and Yemen's Houthis - all recipients of Iranian support - as "entities that present risks to Middle East stability and to Israel".

"They are determined to wipe this country off the face of the planet and we have a moral obligation and a political one to prevent that from happening. You should know that the United States is prepared to do that," Pompeo said in public remarks at the meeting.

Hosting Pompeo at his office, Israeli President Reuven Rivlin said Lebanese Prime Minister Saad al-Hariri “cannot say to anyone that Lebanon is separate from Hezbollah” - a reference to the group’s clout in Beirut where it has ministers in the coalition cabinet as well as lawmakers in parliament.

“If some(thing) will happen from Lebanon towards Israel, we will hold Lebanon as the responsible (party)”, Rivlin said.
