This is the World News from the BBC in London.

Four Americans on board a yacht held hostage by Somali pirates have been killed by their captors. The US Navy said that the crew of one of its warships was negotiating with the pirates when shooting broke out aboard the captured yacht, the Quest. Vice Admiral Mark Fox is the commander of the US Navy’s Fifth Fleet.

“Gunfire erupted inside the cabin of the Quest. Several pirates appeared on deck and moved up to the bow with their hands in the air in surrender. US Naval reaction forces closed in on the Quest and boarded the yacht. As they responded to the gunfire, reaching and boarding the Quest, US sailors discovered that all four hostages had been shot by their captors.”

The American said that they killed two of the pirates and found two more dead on the yacht. The others were captured.

New Zealand's Prime Minister John Key described the centre of Christchurch as “a scene of devastation”.

A mass polio vaccination campaign is being planned in Burma after a 7-month-old baby was found to have the virus. It’s the first case there for three years. Vivien Marsh has this report.

Burma had been on the point of being declared free of polio, a highly contagious virus that can lead to paralysis and which is spread mainly through contaminated food and water. Four years ago, the Burmese government immunised nearly 7 million children. Since a drive to eliminate polio began more than 20 years ago, the number of cases has dropped by 99% worldwide. A team from the World Health Oganisation is already in Burma to work out how to stop its spreading again there.
