A HEREFORD charity worker is helping the relief operation in Burma. Many life-saving aid teams are still waiting for permission to enter the flood-ravaged country to help victims of the cyclone. But one aid worker from Hereford-based Operation Blessing, a Christian aid organisation, has arrived in Burma after managing to secure a visa. The organisation has not named the man but administrator Peter Darg confirmed he was a former pupil of Hereford Cathedral School who would be providing medical aid to the victims and help supply food and water. Sources inside Burma have estimated that the death toll could be higher than 100,000 but there are fears that starvation and disease push it up to 500,000 in the coming weeks. It is now a week since the 120mph winds of Cyclone Nargis swept huge waves inland. Operation Blessing International (OBI) was formed in 1978 to help alleviate human suffering around the world.
