The anthrax threat? Ask the BBC's correspondents. Watch the forum live 56K

Confirmed cases of anthrax in the United States have sparked panic across the world.

Citizens have been warned to look out for suspicious packages or envelopes possibly containing the deadly substance, which has already claimed one life in the United States.

If you have any questions about the threat posed by anthrax across the world or what individual countries are doing to maximise security against possible attacks, send your questions to our panel and they will answer a selection of them.

The global forum on anthrax will be presented by the BBC's Diplomatic correspondent Bridget Kendall, who will be joined by Jacky Rowland in Northern Afghanistan, Tim Franks in Washington and the BBC's health correspondent in London, Neil Bennett. It will be broadcast live on TODAY at 1430 BST.
