Prime Minister Benjamin Netanyahu condemned the suicide bombing that killed 31 at Moscow's busiest airport on Monday, telling Russian President Dmiry Mevedev that Israel stood behind its efforts to fight terror.
Germany's Foreign Minister Guido Westerwelle said he had "heard of the attack with shock," and added, "I condemn this vile bloodshed in the strongest terms. Nothing can justify this barbaric act. We offer our condolences to the relatives and friends of the victims."
U.S. President Barack Obama also condemned the attack and offered to extend any assistance to Moscow that it requires in connection with airport attack.
"I strongly condemn this outrageous act of terrorism against the Russian people," Obama said in a statement read by White House spokesman Robert Gibbs.
The blast, which hit Moscow-Domodedovo Airport during the busy later afternoon, also injured about 130 people during the busy late afternoon.
Security has been beefed up at Moscow's other two airports, which will also receive diverted passengers who were flying toward Domodedovo, media reported.
Secretary of State Hillary Clinto joined Obama strong remarks and declared: "We stand with the people of Russia in this moment of sorrow and we offer our deepest sympathy to the families and loved ones of those injured and killed."
"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," she said.
"The United States remains ready to support the Russian government as it seeks to bring these perpetrators to justice," she added.
