Clinton: 'The Syrian government is running out of time'

US Secretary of State Hillary Clinton has warned time is running out for Syria's government to usher in reforms.

She said President Assad would face more organised resistance to his rule unless the country saw "a genuine transition to democracy".

Human rights groups estimate that about 1,700 people have been killed in three months of anti-government protests.

"We know what they have to do," Mrs Clinton said at a news conference during a visit to Lithuania.
