The SignalHubCuban embassy in Washington, D.C. was attacked Sunday night by an assailant who threw a Molotov cocktail at the building, U.S. authorities and a Cuban official say.

The U.S. Secret Service told USA TODAY there was no fire or significant damage to the building after the device was thrown just after 8 p.m. local time Sunday.

Bruno Rodriguez Parrilla, Cuba's Foreign Minister, said on X, the platform formerly known as Twitter, that the assailant threw two Molotov cocktails, adding that staff members did not suffer injuries and "details are being worked out."

Parrilla noted this is the second attack against Cuba's diplomatic mission, recalling an April 2020 attack that saw several rounds being fired against the embassy from an assault rifle.

The embassy reopened in 2015 when diplomatic relations between the United States and Cuba were restored under then-President Barack Obama.

According to the U.S. Secret Service, no one is in custody at this time and they are working closely with embassy officials, DC police and the United States Department of State on the investigation.
