The United States has offered assistance to Russia in the wake of today's suicide bomb attack at a Moscow airport, which President Obama condemned as an "outrageous act of terrorism against the Russian people."
The blast killed at least 35 people and injured more than 130, according to Russian news reports.
"I strongly condemn this outrageous act of terrorism against the Russian people," White House press secretary Robert Gibbs said in a statement from Obama at the White House press briefing. “We share your sorrow and resolve to stand with you."
Secretary of State Hillary Rodham Clinton also said in a statement: "The United States condemns terrorism and all forms of violence against the innocent, wherever it occurs. We stand with the victims of these crimes, and we will continue to work with the international community to combat violent extremism that threatens peace-loving people everywhere.
"The United States remains ready to support the Russian government as it seeks to bring these perpetrators to justice."
State Department spokesman P.J. Crowley said the United States had offered support in that effort and that such assistance, if needed, would most likely include the dispatching of FBI agents to help with the Russian investigation.
Gibbs said National Security Adviser John Brennan briefed the president at 10:45 a.m. today. Crowley said that at this point, the U.S has not received word that any American citizens were killed or injured in the attack.
