This was in reference to the recent phone conversation between the leaders of two countries, which took place a day before the reconciliation talks on the Ukrainian crisis in Minsk.
"Obama is urging Putin to peace and threatening," the German newspaper "Die Zeit" wrote. According to the newspaper, the US president told Vladimir Putin that he would have to pay a high price if the conflict is not settled.
"Der Spiegel" magazine also noted that Obama's calls for peace contained a threatening tone. The US leader once again accused Russia of military involvement in the Ukrainian conflict. If Russia continues its "aggressive actions" in Ukraine and provides independence supporters with weapons and financial assistance, then "the costs for Russia will rise", Obama warned.
The US recently announced that it is considering the possibility of supplying Ukrainian troops with lethal weapons.
The issue of direct US military assistance still remains on the US agenda, the Swiss newspaper "Blick" wrote, adding, however, that European countries such as Germany, the UK, Denmark, Austria and Sweden oppose the idea of US involvement in the Ukrainian crisis.
