Lebanese President Joseph Aoun will meet U.S. President Donald Trump at the ​White House on Tuesday to present a plan on how to disarm Iran-backed militant group Hezbollah and secure Israel's withdrawal from Lebanon.

Axar.az reports, citing Reuters, Aoun, who served as the commander of Lebanon's ‌U.S.-backed army before being elected president last year, is the first Lebanese head of state in nearly 20 years to visit the White House, where he will meet Trump face-to-face for the first time.

The meeting comes at a crucial moment for Lebanon: Israeli troops are occupying a swathe of the country's south, hundreds of thousands of Lebanese remain displaced following Israeli strikes and Hezbollah has firmly rejected the government's direct talks with Israel -- and efforts by the state to strip it of its arms.

Aoun arrived ​in Washington at the weekend and met with U.S. Secretary of State Marco Rubio on Sunday, telling him that Israel should begin withdrawing from southern Lebanon in line with a U.S.-brokered June ​26 agreement between Lebanon and Israel.
