"A fake text message warning people that radiation from the Fukushima nuclear plant has leaked beyond Japan has been panicking people across Asia.
The SMS message, purporting to come from the BBC, has been circulating around Asian countries since Monday.
It warns people to take necessary precautions against possible effects of radiation.
The BBC has issued no such flash but the hoax has caused particular panic in the Philippines.
Some media reports suggest that workers and school children there were sent home after the rumours began to spread, prompting the Philippines government to issue an official denial."
