The White House on Sunday confirmed that Russian President Vladimir Putin called President Trump to thank him.

Responding on Twitter to a report that said Putin called Trump "to thank him for a CIA tip that thwarted bombings," White House press secretary Sarah Sanders confirmed the report and said the White House would follow up with more information.

The two leaders also spoke Thursday and on the call, the White House said Trump "thanked President Putin for acknowledging America’s strong economic performance" earlier in the day.

The Associated Press reported Friday Russian authorities arrested seven people claiming to be members of the Islamic State who were planning bombings in St. Petersburg during the weekend.

The AP reported authorities searched a St. Petersburg apartment and found explosives, automatic weapons and extremist literature.
