Mass demonstrations against Cuba's Communist government have taken place on the island.
Campaigners shouted "Down with the dictatorship" during Cuba's largest protests for three decades.
Photos show police using pepper spray and beating protesters.
Cubans have been angered by the collapse of the economy, food shortages and high prices, as well as restrictions on civil liberties by the communist regime.
The country has also seen record Covid-19 infections in recent days.
Last year, Cuba's economy shrank by 11 percent when it was hit by the pandemic and US sanctions imposed by the Trump administration.
Miami mayor Francis Suarez led demonstrations in the Florida city, which has the US’s largest Cuban population, and urged President Biden’s government to intervene.
He tweeted: "The Cuban regime’s military police are shooting at unarmed Cuban protestors fighting for freedom. Sixty years of communism, cruelty and oppression cannot last any longer.
"We are imploring the USA to take action as we peacefully demonstrate on the streets of Miami."
Cuban President Miguel Díaz-Canel said the protests were by mercenaries hired by the US to weaken the country.
He promised a "revolutionary response".
