MOSCOW, Sep. 26 (TASS) - Russia resolutely condemns the recent attack on the Cuban embassy in the United States and insists that a probe into the circumstances behind it be conducted as soon as possible, Russian Foreign Ministry Spokeswoman Maria Zakharova said in a comment.

"We resolutely condemn the September 24 attack on the embassy of Cuba in the United States at which two Molotov cocktails were reportedly thrown," the Russian diplomat said. "[The attack] must not be left unpunished and those responsible for it should be punished heavily," Zakharova said, as she urged Washington to conduct a thorough probe into the incident as soon as possible.

According to Zakharova, the latest incident is not the first such crime against the Cuban diplomatic mission in Washington which came amid what she said was "the atmosphere of ongoing threats against the government of the Island of Freedom."

"Once again we call on the host country to unconditionally ensure the security of foreign diplomatic missions on its territory in strict compliance with international obligations. We express our solidarity with the brotherly people of the Republic of Cuba and our full support for their government," the diplomat said.
