Burma's cyclone death toll soars

The death toll from Burma's devastating cyclone has now risen to more than 22,000, state media have said.

Some 41,000 are also missing three days after Cyclone Nargis hit the country, causing a huge tidal surge to sweep inland, according to state radio.

The report came as aid agencies begin what they expect to be a major relief operation to help tens of thousands left without clean water and shelter.
