The United States has said it is ‘deeply troubled’ by the conviction of Egyptian opposition leader Ayman Nour on forgery charges and has called for his release.

A court in Cairo sentenced Ayman Nour to five years in prison.

Mr Nour, the runner-up in last September's presidential election, was accused of forging documents to register his political party. 

He was detained earlier this month and underwent hospital treatment after going on hunger strike.

The Vice-President of his political party, Yusham Kassim, said he believed the trial was politically motivated.
