(Reuters) - Ukraine's leader called for solidarity on Thursday, a month after Russia's invasion began, warning he would see who sells out at summits in Europe, where plans to bolster sanctions and NATO are afoot but restrictions on energy could prove divisive.
U.S. President Joe Biden has arrived in Brussels for meetings of the alliance, G7 and EU over a conflict that began on Feb. 24 and has caused more than 3.6 million refugees to flee the country.
