Haiti quake aid effort hampered by blockages

Bottlenecks and infrastructure damage have been holding up aid efforts in Haiti, where a devastating earthquake has left as many as 45,000-50,000 dead. Aid has been arriving from around the world, but there is little sign of help beyond the airport, correspondents say.

Many are spending a third night without shelter or in makeshift camps in the ruined capital, Port-au-Prince. US President Barack Obama pledged a huge aid effort, but warned it would take time for help to reach people. President Obama and French President Nicolas Sarkozy, working with Brazil, Canada and other countries, will organise a conference on reconstruction in Haiti, the French presidency has announced.
