Troubling reports out of Russia are raising questions about the safety of next month's Winter Olympics in Sochi.

Two bombings in Volgograd, in southern Russia, killed 34 people last month. A video in which two men claimed responsibility for the suicide attacks was just released by a terror organization, Vilayat Dagestan, which is based in Russia's restive Caucasus region.

The men promised more bombings during the Olympics.

In addition, U.S. and Russian forces are on the hunt for at least four so-called "black widows" - women who join terror groups after the death of their husband.

One in particular, 22-year-old Ruzanna Ibragimova, is believed to have traveled from Dagestan to Sochi recently.

Russia has deployed a 40,000-strong security force to patrol a 1,500-mile security zone around Sochi in a bid to ensure the safety of the athletes and tourists.

This morning on Fox and Friends, Fox News legal analyst Peter Johnson Jr. discussed the terror alerts with Steve Doocy, who asked whether the United States can trust Russia to protect Americans.

Johnson called on U.S. officials to come together and make a determination about the safety of the Games. If the area is deemed unsafe, U.S. athletes should not compete, he said.
