Some members of the energy alliance OPEC+ are considering whether to suspend Russia from an oil production deal, The Wall Street Journal reported on Tuesday, citing unnamed OPEC delegates.

This comes at a time when non-OPEC leader Russia, a major player in global energy markets, faces a barrage of Western sanctions and a partial oil ban from the European Union in the wake of the onslaught in Ukraine.

OPEC delegates are reportedly concerned about the growing economic pressure on Russia and its ability to pump more crude to cool soaring prices.
