Russia sends purported aid trucks to Ukraine as NATO secretary-general issues new attack warning

Russia said Tuesday that it had dispatched 280 trucks full of humanitarian aid to eastern Ukraine, after NATO's secretary-general warned that there was a "high probability" that Moscow would order troops to the war-torn region to aid separatist rebels. 
Russian television reported early Tuesday that trucks carrying 2,000 tons of humanitarian aid were headed to Ukraine. Reporters said the convoy of trucks, painted white and bearing a red cross, is part of an internationally agreed-upon mission under the auspices of the International Committee of the Red Cross.
NTV television showed hundreds of white trucks gathered at a depot outside Moscow, and said they were carrying everything from baby food to sleeping bags. A Russian Orthodox Priest sprinkled holy water on the trucks, some of which bore a red cross, before their departure. They could take up to a day to arrive at their destination.
However, Andre Loersch, a spokesman for the Red Cross in Kiev, told The Associated Press by phone that despite the general agreement among all parties, he had "no information about the content" of the trucks and did not know where they were headed.
"At this stage we have no agreement on this, and it looks like the initiative of the Russian Federation," he said.
The Ukrainian Foreign Ministry said it was not immediately able to comment on the convoy.
Western officials have repeatedly expressed fears that any Russian aid mission would serve as a precursor to action by Russian ground troops. Late last week, U.S. President Barack Obama, German Chancellor Angela Merkel, and British Prime Minister David Cameron issued statements proclaiming that such action would violate international law. 
However, Ukraine said Monday that it had agreed to send aid to the city of Lunhansk, one of two major rebel enclaves that are still holding out despite being battered by fighting. After announcing the aid mission on Monday, U.S. President Barack Obama and Ukrainian President Petro Poroshenko agreed that "any Russian intervention in Ukraine without the formal, express consent and authorization would be unacceptable and a violation of international law," according to a White House statement.
Also on Monday, NATO Secretary-General Anders Fogh Rasmussen told Reuters that there were no signs that Russia had withdrawn any of its troops amassed at the border with Ukraine. When a reporter asked him about the possibility of a Russian invasion, Rasmussen said, "There is a high probability.
"We see the Russians developing the narrative and the pretext for such an operation under the guise of a humanitarian operation, and we see a military build-up that could be used to conduct such illegal military operations in Ukraine," he added.
Also Monday, Ukraine's military claimed that the numbers of Russian troops along the border had risen dramatically. Spokesman Andriy Lysenko claimed to The New York Times that Russia had 45,000 troops at the frontier supported by 160 tanks, 1,360 armored vehicles, 390 artillery systems, 150 truck-mounted ground-to-ground rocket launchers, 192 fighter jets and 137 helicopters. Lysenko's estimates had not been independently verified. NATO has previously estimated that 20,000 Russian troops have gathered at the border. 
The United Nations has estimated that more than 1,300 people have been killed since April, when government forces launched a campaign to recapture eastern Ukraine from rebels who had gained control of two provinces under the banner of the Putin-coined term "New Russia."
The other major separatist-controlled city, Donetsk, has been under heavy bombardment from Ukrainian forces. Lysenko said that Ukrainian forces were moving closer to encircling the city. At least 300,000 civilians, encouraged by Kiev, are believed to have fled the city, which formerly had a population of 1 million. Residents who have stayed say that mortar and artillery fire can be heard daily. There have been civilian casualties, though estimates vary widely.
