MOSCOW, May 7 (Reuters) - Russian Deputy Prime Minister Alexander Novak said on Tuesday that the OPEC+ group of leading oil producers had already agreed to act on oil production is necessary, the Interfax news agency reported.

He also said there was no need to predict further OPEC+ steps, while the situation on the market should be analyzed.

OPEC and its allies have yet to begin formal talks on extending voluntary oil output cuts of 2.2 million barrels per day beyond June, but three sources from OPEC+ producers have said they could keep their cuts if demand fails to pick up. (Reporting by Vladimir Soldatkin, Editing by Louise Heavens)
