The U.S. military said on Monday that air and naval assets, including two ships in the Black Sea, would be made available if needed during the Sochi Winter Olympics in support of Russia, which faces militant threats to disrupt the Games.

The Pentagon said U.S. military commanders were “conducting prudent planning and preparations” should American support be required during the Winter Olympics.

“The United States has offered its full support to the Russian government as it conducts security preparations for the Winter Olympics,” Pentagon spokesman Rear Admiral John Kirby said in a statement.

“Air and naval assets, to include two Navyships in the Black Sea, will be available if requested for all manner of contingencies in support of – and in consultation with – the Russian government.”

The Pentagon statement came the same day that two men said by Islamist militants to have carried out suicide attacks in south Russia appeared in a video donning explosive belts and warning Russian President Vladimir Putin to expect a “present” at the Sochi Winter Olympics from fighters following after them.

Reuters reported on Sunday that U.S. military and intelligence officials have been studying contingency plans for evacuating Americans from the games in case of a crisis.

But U.S. officials have concluded there would be major obstacles to mounting a large-scale effort by the military or other U.S. government resources to evacuate Americans from Sochi,
