A powerful earthquake has struck the Caribbean nation of Haiti, killing at least 227 people.

The 7.2-magnitude quake hit the west of the country on Saturday morning, toppling and damaging buildings including churches and hotels. The prime minister said there was "extensive damage" in some areas, and declared a month-long state of emergency.

 

Haiti is still recovering from a devastating 2010 earthquake. The epicentre of Saturday's quake was about 12km (7.5 miles) from the town of Saint-Louis du Sud, the US Geological Survey (USGS) said.

The tremor was felt in the densely-populated capital of Port-au-Prince, some 125km away, and in neighbouring countries.

Prime Minister Ariel Henry said he had mobilised a team to work on the relief effort. He also appealed to Haitians to unify as they confront what is a dramatic situation in which they are living right now. US President Joe Biden authorised an immediate US response to help the country.

The USGS earlier warned that the earthquake could result in thousands of fatalities and injuries. It also said at least six aftershocks had been felt in the region including one measuring 5.1 magnitude.

Frantz Duval, editor-in-chief of Haiti's Le Nouvelliste newspaper, tweeted that two hotels were among the buildings destroyed in the town of Les Cayes. He said the local hospital was overwhelmed.

"Slowly, strongly and for very long seconds the earth shook in Haiti on 14 August, 2021 around 8:30 am," he wrote.

Reporters at Le Nouvelliste later said the majority of churches and hotels on the south coast had collapsed or suffered major damage. Photos shared on social media showed damaged buildings and piles of rubble after the quake.

Haiti director of Save the Children, Leila Bourahla, said that it would take days to assess the damage but that it is clear that it is a massive humanitarian emergency. The 2010 earthquake in Haiti killed more than 200,000 people and caused extensive damage to infrastructure and the economy.

The earthquake comes amid a political crisis in the country, following the assassination of its president last month.
