Food and water are finally reaching some parts of the Haitian capital Port-au-Prince, but relief efforts are being slowed by bottlenecks. Some aid flights are not being allowed to land at the city's airport and large numbers of earthquake survivors are having to fend for themselves.

Today correspondent Mike Thomson spoke to medical administrator Michael Goebel, who has been averaging just two hours' sleep a night trying to identify bodies pulled from the rubble before moving them to a makeshift mortuary. "The people who are dying are from a two-year old little Haitian girl who couldn't get her last breath to the very leadership of our own UN mission," he explained.

"So mother nature is not discriminating at all."

In a nearby town, still best by aftershocks, one woman sat in the ruins on her three-floor house. "My house is destroyed. I don't have a husband. I have no-one," she says.

And the sight of bodies being loaded into a large truck indicates that this is "death on an industrial scale".
