Tens of thousands protested across the country yesterday, demanding that their former President be put on trial.
Ali Abdullah Saleh stepped down last month in a deal that protected him from prosecution, but he is still in Yemen. The government has said at least 2,000 people have been killed in a year of turmoil. Protesters want the immunity deal cancelled so that Mr Saleh and his relatives can be put on trial for the killings.
Mr Saleh was expected to leave Yemen, but critics say he is still interfering in the government.
