Hariri supporters protest against Hezbollah-led government

An American-educated billionaire, Najib Mikati, has been appointed prime minister of Lebanon, despite an outcry by supporters of his predecessor Saad Hariri.

Mr Mikati's backers, the militant Hezbollah group and its allies, secured enough votes in parliament to get him nominated.

Mr Hariri has appealed for calm as thousands of his supporters staged street protests against what they describe as a coup by Hezbollah.
