Confirming the incident, Spokeswoman Emilia Casella said that the World Food Programme"s warehouses which were in place prior to the earthquake were raided.
The incident comes as major blow to Haiti as UN has already been struggling with proving food relief to around 2 million people.
“At this point we are trying to get the food we have our hands on to the people," Casella said.
She informed that the supplies were dropped to the survivors in a bucket.
Meanwhile, Elizabeth Byrs, a spokeswoman for the UN Office for Coordination of Humanitarian Affairs, said that there is enough search and rescue teams.
“So far we have enough search and rescue teams. Some 40 teams have registered through our centre and are mobilized," she said.
Byrs added that additional team was not required as field hospitals have already arrived.
“Priority for the moment is medical teams, nurses, surgeons for trauma and medicines of all sorts," Byrs said.
