U.S. condemns attack in St. Petersburg Metro

The United States on Monday condemned the attack on the metro system in St. Petersburg, Russia, while pledging to provide assistance to Russia in its investigation.

"The United States condemns this reprehensible attack and act of violence," White House spokesman Sean Spicer told a news briefing, while extending "our deepest condolences to the loved ones who have been killed and injured."

At least 11 people have been killed and dozens of others wounded in an explosion that took place Monday in a train carriage on the runway between the metro stations Technological Institute and Sennaya Ploshchad (Square) in St. Petersburg.

The exact causes and who were responsible for the attack remain unknown pending an official investigation. Russian officials described the bombing as an act of terror.

"Attacks like these on ordinary citizens just going about their lives remind us that the world must work as one to combat violence in all forms," Spicer said, adding that the U.S. is prepared to offer assistance to Russia that it may require in investigating this crime.

U.S. President Donald Trump was earlier briefed on the attack on the St. Petersburg Metro, Spicer said.

Trump, speaking before having a lunch with visiting Egyptian President Abdel Fattah El-Sisi in the White House, called the bombing a "terrible thing."

"Terrible. Terrible thing. Happening all over the world," Trump said in response to a media question, without making further comments. Endit
