HAVANA (AP) — Cuba has condemned a deadly attack on a U.S. diplomatic mission in Libya.

The Foreign Ministry statement is a rare show of solidarity with the island's Cold War enemy to the north, particularly concerning a part of the world where their differences could not be greater.

Cuban President Raul Castro and his brother, Fidel, were staunch allies of Libyan strongman Moammar Gadhafi and deplored the NATO-supported uprising that toppled him.

The Foreign Ministry's statement condemns the attack in Benghazi, Libya, that killed the U.S. ambassador and three other Americans. It says violence against diplomats is not justified "anywhere, or under any circumstances."
