Espiões dos EUA ajudam a evitar ataque terrorista na Rússia

Information provided by the CIA helped to prevent a series of terrorist bombings in St Petersburg, Russia.

Vladimir Putin phoned Donald Trump to thank him for the tip-off, the Kremlin said.

The information allowed Russian security services track down and detain a group of suspects who were planning bomb attack on the Kazansky Cathedral and other sites in Russia's second-biggest city.

The Kremlin said the Russian President asked his US counterpart to convey his gratitude to the CIA.

He also said Russian security agencies would continue to hand over any information they get about potential terror threats against the United States.

Russia's FSB security service said seven people were arrested and a significant amount of explosives and weapons seized. 

The cell was said to be planning to carry out a suicide attack on Saturday, 16 December.

The conversation was the second phone call between the two leaders since Thursday, when the Mr Trump thanked Mr Putin for his remarks "acknowledging America's strong economic performance," according to the White House. 

During the first call, they also discussed ways to work together to address North Korea's nuclear and ballistic weapons programme, the White House said.
