Ukraine's Ambassador to the UK has accused Russia of "direct and open involvement" in the conflict in eastern Ukraine.
Ambassador Andrii Kuzmenko assured ITV News that "Ukraine will cope with this crisis" but added that "military technical" and "financial" assistance were needed.
President Vladimir Putin has said Russia will continue to provide humanitarian aid to civilians in eastern Ukraine, the Kremlin announced.
He is also reported to have ordered separatist rebels to provide a humanitarian corridor for encircled Ukrainian troops to exit.
US President Barack Obama has warned that Russia faces "more costs and consequences" if it continues to aid rebels in eastern Ukraine.
In a news conference at the White House, he said:
– president Obama
The violence is encouraged by Russia. The separatists are trained by Russia. They are armed by Russia. They are funded by Russia. Russia has repeatedly and deliberately violated the sovereignty and territorial integrity of Ukraine, and the new images of Russian forces inside Ukraine make that plain for the world to see ...
As a result of the actions Russia has already taken, and the major sanctions we have imposed with our European and international partners, Russia is already more isolated than at any time since the Cold War ... This ongoing Russian incursion into Ukraine will only bring more costs and consequences for Russia.
Fifteen civilians were killed after Donetsk came under more heavy shelling today, according to city authorities.
People ran for shelter after shells fell on a market area of the eastern Ukrainian city. Emergency services rushed to carry away the casualties and out out fires in apartment buildings and cars.
Some apartment buildings showed signs of extensive damage from two weeks of shelling as Ukrainian forces try to wrest the city from the grip of pro-Russia rebels.
Local media agencies also distributed footage purporting to show civilians killed by shelling in the streets.
State Department spokeswoman Jen Psaki has said the US is considering a "range of tools" to deal with what it sees as Russian aggression in Ukraine.
She said increased sanctions on Russia are "the most effective tool, the best tool."
"A military solution is not what we think is the appropriate approach so we're taking every tool that we can to see if we can reach a solution here through diplomatic means," she said.
The US State Department says it has observed a "pattern of escalating aggression" by Russia in Ukraine.
Nato has released satellite images that it says show Russian combat troops and "sophisticated heavy weaponry" inside Ukraine.
The images were taken in late August and reportedly show "self-propelled artillery" moving in convoy and establishing firing positions near the city of Krasnodon in eastern Ukraine.
In a statement, Nato said the images provide "concrete examples of Russian activity inside Ukraine" but represent "only the tip of the iceberg in terms of the overall scope of Russian troop and weapons movements".
Nato also said other images show Russian forces transferring weapons and other military hardware to separatist forces, and "substantial activity" on the Russian side of the border with Ukraine.
Fifteen civilians have been killed in shelling in the east Ukrainian city of Donetsk today, the city administration said in a statement on its website which described the general situation there as "very tense".
Reports that Russian military units are in Ukraine bear "no relation to reality," according to the Russian defence ministry cited by the Interfax news agency.
The Canadian delegation to Nato has come up with this response to reports that Russian troops entered Ukraine "by mistake".
The sarcastic tweet, which attracted claims that Canada has "trolled" Russia, has been re-tweeted more than 17,000 times.
On Tuesday, an unnamed Russian security source was quoted as saying the incursion was a "mistake" - a claim contradicted by Ukraine which says the troops have attacked the eastern town of Novoazovsk.
