Lebanon's lawmakers have elected army chief Joseph Aoun as president, ending a two-year vacancy in the position. Aoun faces the challenges of overseeing a ceasefire in south Lebanon and naming a prime minister to lead reforms to save the country from its economic crisis. He vows to call for discussing a comprehensive defence strategy and wants the state to have 'a monopoly' on arms. Aoun is Lebanon's fifth army commander to become president and the fourth in a row.
