The new unity government in Tunisia appears to be in danger of falling apart just a day after it was formed. At least three ministers, all with strong trade union links, have already resigned, and others are threatening to go. Our correspondent Wyre Davies is in Tunis.

Barely a day after the interim unity government was announced, it was in real danger of collapse as three ministers from Tunisia's labour movement withdrew. The junior ministers and their supporters said they could not be part of an administration in which several members of the former authoritarian government had been given prominent positions. As more pro-democracy protests in Tunis and across the rest of the country again turned violent, a stable transition to open and democratic government is by no means certain.

The former Haitian leader Jean-Claude Duvalier, also known as "Baby Doc", has been detained by police two days after his surprise return to Haiti after 25 years in exile. Earlier, the Haitian authorities said they were going to question him to determine whether he should be prosecuted for stealing from the treasury. Andy Gallacher reports.

Jean-Claude Duvalier has been at the Karibe Hotel in Port-au-Prince since his surprise return to Haiti on Sunday. Dozens of Haitian police officers have been posted both inside and outside the building, and it's reported that the former dictator met with senior judicial figures on Monday night. Now he's been taken into custody by the police, but it's not clear whether Mr Duvalier has been arrested or if he'll be charged with any crimes. Eyewitnesses say the 59-year-old wasn't in handcuffs. Mr Duvalier, or "Baby Doc" as he's also known, was forced into exile in 1986 following a mass uprising.
