Lebanon's newly elected president, Joseph Aoun, said Thursday that "a new phase" has started for the war-ravaged country and pledged to rebuild the state, adopt a policy of "positive neutrality" and fight corruption.

General Joseph Aoun was widely seen as the preferred candidate of the United States, which funds, trains, and arms the Lebanese military and helped broker a cease-fire between Israel and the militant group Hezbollah in November.

Lebanon's parliament elected army chief Joseph Aoun head of state on Thursday, filling the vacant presidency with a general who has U.S. support and showing the weakened sway of the Iran-backed Hezbollah group after its devastating war with Israel.
