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 and caused a huge tidal surge to sweep inland, state radio said.

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

Burma's military government has been criticised over its crisis management.
