The 3-day period during which the body of Nelson Mandela lay in state has come to an end. South African officials say around 100,000 mourners have viewed Mr. Mandela's body at the union buildings in Pretoria. Some had to be turned away because queues were too long. Peter Biles reports from Pretoria.

In the Sandstone Amphitheater that is soon to be on Nelson Mandela's name, three days of lying in state ended with the playing of the South African National Anthem Nkosi Sikelel' iAfrika. From the spot where Mr. Mandela was sworn in as president in 1994, his coffin was carried down the steps to the waiting hearse as military helicopters circled over the city. The body will remain in Pretoria overnight, and there will be a ceremony at a local air force base in the morning to allow members of the governing African National Congress to say a last farewell before Mr. Mandela's funeral in the eastern Cape on Sunday.

The United States says a retired FBI agent who is believed to have been held in Iran for the last 7 years was not a government employee when he went missing. US media have said that Mr. Levinson was on an unauthorized CIA intelligence operation when he went missing on the Iranian island of Kish. From Washington, here is our correspondent Jonny Dymond.

In a carefully phrased response to the Associated Press's story, White House spokesman Jay Carney said that Robert Levinson was not a government employee at the time of his disappearance. Mr. Carney also criticized as irresponsible the publication of the story. The AP said that Mr. Levinson was on an informal mission for the CIA organized by a group of agency officers outside of the normal oversight procedures. Mr. Levinson was last heard from in a video made public in the early 2011 where looking gaunt and sounding weary, he asked for US government assistance.

Mr. Levinson's family has criticized the US government, saying some officials were failing to do their best to locate him.

Scientists say a mud volcano in Indonesia that's displaced tens of thousands of people should stop erupting much sooner than previously thought. The assessment is based on satellite monitoring of the area around the Lusi Volcano in east Java. Here is our science correspondent Jonathan Amos.

The eruption which began in east Java in 2006 is the largest of its kind, the result of a drilling operation that went wrong. The gooey noxious muck spewing out from the earth has so far displaced tens of thousands of people and has to be controlled by huge dams. Initially more than 100,000 tons of mud oozed to the surface each day. This has decreased ten fold and a new analysis based on Japanese satellite observations of ground subsidence suggest a further ten fold decrease can by expected by 2017.
