Cuban authorities have confirmed that a man was killed during unrest in the country - the first confirmation of a death since the protests broke out.

State media say Diubis Laurencio Tejeda, 36, died in a suburb of the capital Havana on Monday.

According to officials, he was part of a group that attacked a government facility. But witnesses say security forces targeted members of the group.

The rare nationwide anti-government protests began on Sunday.

Thousands took to the streets to demonstrate over the collapse of the economy, food and medicine shortages, price hikes and the government's handling of the Covid-19 epidemic. Such unauthorised public gatherings are illegal in Cuba.

President Miguel Díaz-Canel has called demonstrators "counter-revolutionaries".

His government alleges that the protests have been financed and instigated by the United States, and blames Cuba's problems on US economic sanctions.

What do we know about the death?

As yet there is no official explanation for how Diubis Laurencio Tejeda died. Cuba's interior ministry said in a statement that it "mourns the death" of the man.

State media said he was involved in "disturbances" in the La Guinera neighbourhood of Havana on Monday, where a group allegedly attacked a government facility, state media reported. Several others were injured, including members of the security forces, it said.

But witnesses have said that it was the security forces that attacked people who had joined a spontaneous protest in the neighbourhood.

Waldo Herrera, who lives in the area, told Reuters news agency that officers "took out their guns and started shooting" at the demonstrators.

"I think the Communists have lost control, they won't have a solution to this situation," he told Reuters.
