Syria's President takes oath after criticised re-election

Assad was sworn in on the constitution and the Koran in the presence of more than 600 guests, including ministers, businessmen, academics and journalists, organisers said.

The vote extending Assad's grip on power was the second since the start of a decade-long civil war that has killed more than half a million people, displaced millions and battered the country's infrastructure.

On the eve of the May 26 election, the United States, Britain, France, Germany and Italy said the poll was "neither free nor fair", and Syria's fragmented opposition has called it a "farce".

With his campaign slogan, "Hope through work", Assad cast himself as the sole architect of a reconstruction phase for the troubled country.
