Russia on Friday strongly repeated its demand that NATO will not expand eastward, despite the rejection of that by the military alliance amid a Russian troop buildup near Ukraine, writes ABCNEWS.

It added that it wouldn"t wait indefinitely for the Western response.

Foreign Minister Sergey Lavrov on Friday described Moscow’s demands that NATO will neither expand nor deploy forces to Ukraine and other ex-Soviet nations as essential for the progress of diplomatic efforts to defuse soaring tensions over Ukraine.

He argued that the deployment of NATO forces and weapons near Russia’s borders poses a security challenge that must be addressed immediately.

“We have run out of patience”, - Lavrov said at a news conference. “The West has been driven by hubris and has exacerbated tensions in violation of its obligations and common sense”.

Lavrov said that Russia expects Washington and NATO to provide a written response to its demands next week.

Amid the tensions, Ukraine sustained a massive cyberattack Friday, which hit websites of multiple government agencies.

This week’s negotiations in Geneva and a related NATO-Russia meeting in Brussels were held amid a significant Russian troop buildup near Ukraine that the West fears might be a prelude to an invasion.
