Aoun secured 99 votes from the 128-seat parliament to win the presidency on Thursday afternoon. He only needed a simple parliamentary majority of 65 votes in the second round, as reported by Al Jazeera.
Members of parliament erupted in celebration as Aoun reached the number of votes required to be elected.
Earlier in the day, he fell short of the two-thirds majority in the first round of voting.
During the first round, he received support from 71 parliament members, 15 short of the required 86 votes.
The Mediterranean country has been without a president since the term of Michel Aoun – not related – ended in October 2022.
