MOSCOW: Western countries will be running "colossal risks" if they supply Ukraine with F-16 fighter jets, TASS news agency quoted Russian Deputy Foreign Minister Alexander Grushko as saying on Saturday.

Grushko was responding to a question about the implications of providing the jets, which Ukraine has been requesting from NATO countries.

It has not yet won commitments to deliver the planes, but U.S. President Joe Biden told G7 leaders on Friday that Washington supports joint allied training programs for Ukrainian pilots on F-16s, senior U.S. officials said.

"We see that Western countries are still adhering to the escalation scenario. It involves colossal risks for themselves," Grushko was quoted as saying.

"In any case, this will be taken into account in all our plans, and we have all the necessary means to achieve the goals we have set."
