The presidents of Syria and Lebanon have arrived in Qatar for their first official visits to the wealthy Gulf state since taking office. Qatar has been a key backer of the new administration in Damascus and has pledged to support the rehabilitation of Syria's infrastructure. The talks between the Qatari and Syrian leaders covered regional and international developments and ways to enhance security and stability. Lebanese President Joseph Aoun also arrived in Doha for talks with the Qatari emir, as Beirut and Damascus seek to improve relations since the overthrow of Assad.
