LATEST: NATO Secretary-General Anders Fogh Rasmussen has dismissed what he said were Russia's "hollow denials" of involvement in Ukraine's separatist conflict.
He said that "it is now clear that Russian troops and equipment have illegally crossed the border." He said Russia is engaged in "direct military operations in Ukraine." He spoke in Brussels after an emergency NATO meeting to discuss the Ukraine crisis.
Rasmussen said Russia's actions were not isolated but "part of a dangerous pattern over many months to destabilize Ukraine."
He said Russia had supplied rebels with tanks, armor, artillery, and rocket launchers and had fired on Ukrainian troops from both Russian territory and Ukrainian soil.
Rasmussen said he fully respects Ukraine's decisions regarding its security policy and alliance affiliations. He spoke shortly after Prime Minister Arseniy Yatsenyuk said the government in Kyiv would pursue membership in NATO.
Here is today's map of the military situation in eastern Ukraine by the National Security and Defense Council. Looking much more grim for Kyiv:
LATEST: Ukrainian Prime Minister Arseniy Yatsenyuk says the government will ask parliament to consider putting Ukraine back on a path toward becoming a NATO member.
LATEST: Russian Foreign Minister Sergei Lavrov says the West has provided no proof that Russian forces have invaded Ukraine.
Aleksandr Zakharchenko, the leader of pro-Russian separatists in the eastern Ukrainian city of Donetsk, has agreed to let encircled Ukrainian government troops leave the battlefield after Russian President Vladimir Putin called on militia forces to open "a humanitarian corridor." Zakharchenko said his forces would comply on the condition that the Ukrainian government forces hand over their weapons. (Reuters)
More well-equipped pro-Russian separatists of the "Donetsk People's Republic" in Ukraine:
From our news desk:
In a new report, the UN says the conflict in eastern Ukraine has killed nearly 2,600 people since mid-April and notes "serious human rights abuses" including abductions and torture committed "primarily" by pro-Russian separatists.
The report, presented in both Geneva and Kyiv on August 29, also documents violations committed by Ukrainian forces in their efforts to recapture territory from rebels.
The UN said the sharp increase in casualties -- around 36 people each day -- is explained by fighting occurring in densely populated areas.
The report says it is not known precisely how many people remain in captivity in Ukraine but says that as of August 17 at least 468 are believed to be still detained by various armed groups.
The UN's high commissioner for human rights, Navi Pillay, said the "deliberate targeting of civilians is a violation of international humanitarian law, and more must be done to protect them."
