A pastor in Haiti has visited radio and TV stations in a bid to secure government aid for rural residents left without homes or shelter following Saturday's earthquake.

Pastor Roosevelt Milford has broadcast messages asking for help for the people of Les Cayes, forced to camp out in a tent city. He said there is a lack of food, clean water and shelter.

"No one from the government has come here. Nothing has been done," he said in his message as heavy rain hit the island from Tropical Storm Grace.

The country's prime minister, Ariel Henry, flew to Les Cayes, a port town, shortly after the quake promising aid, but frustration has been expressed after sufficient provisions failed to materialise, as reported by The Telegraph. 

Over 2,000 people lost their lives when the 7.2 magnitude earthquake hit on Saturday. Over 12,000 people were injured.

On Wednesday at the small airport in Les Cayes, people gathered around a perimeter fence as aid was loaded into trucks and police fired warning shots to disperse a crowd of young men.

Angry crowds also gathered at collapsed buildings in the city, asking for materials for temporary shelters.

One of the first food deliveries by local authorities to one of the poorest areas of Les Cayes included boxes of rice and bagged meal kits.

The shipment was insufficient for the hundreds who have lived under tents for days. "It's not enough, but we'll do everything we can to make sure everybody gets at least something," Vladimir Martino, a camp resident who took charge of the distribution told PA.
