The World Health Organization has warned that over half of the people in Europe are on track to contracting the fast-moving Omicron variant of the coronavirus in the next two months.

A source close to the Vienna talks has told Press TV that negotiations held overnight and Friday between the P4+1 and Iran were based on the draft proposals submitted by the Iranian team last week.

The website of Iran's top security body says the Europeans’ lack of initiative in the face of the Iranian team’s “groundbreaking” proposals is dragging down negotiations in Vienna.
