An injured woman is helped after being rescued on January 13, 2010 in Port-au-Prince, Haiti. Planeloads of rescuers and relief supplies headed to Haiti Wednesday as governments and aid agencies launched a massive relief operation after a powerful earthquake that may have killed thousands. US President Barack Obama ordered a swift and aggressive US rescue effort, while the European Union activated its crisis systems and the Red Cross and United Nations unlocked emergency funds and supplies for the destitute nation. Much of Port-au-Prince was reduced to rubble by the 7.0-strong quake on January 12 but the airport was operational, opening the way for international relief aid to be ferried in by air as well as by sea.
