By late October 2014, many banks and other businesses in the Donetsk People's Republic were shut and people were often left without social benefits payments. Sources (who declined to be identified, citing security concerns) inside the DPR administration have told Bloomberg News that Russia transfers 2.5 billion Russian rubles ($37 million) for pensions every month. By mid-February 2016 Russia had sent 48 humanitarian convoys to rebel-held territory that was said to have delivered more than 58,000 tons of cargo; including food, medicines, construction materials, diesel generators and fuel and lubricants. President Poroshenko called this a "flagrant violation of international law" and Valentyn Nalyvaychenko said it was a "direct invasion".
