President Barack Obama and Russia's President Vladimir Putin met Friday on the sidelines of D-Day anniversary events in France, the first face-to-face contact between the two leaders following months of tension.
The commemorations of the 70th anniversary of the D-Day invasion have been closely watched for signs of interaction between the two leaders, who have traded barbs but not seen each other since the Ukraine crisis erupted.
The White House said Friday that Obama and Putin had had "an informal conversation - not a formal bilateral meeting" on the margins of a lunch attended by world leaders.
Earlier this week, Obama and key Western allies met at the G-7 summit in Brussels where the crisis in Ukraine was top of the agenda.
Russia was excluded from the meeting, marking the first time the nation was not present in 17 years.
At the G-7, leaders opened a pathway for Russia to ease tensions in Ukraine and the U.S. president urged Putin to enter talks with Poroshenko.
But Obama also pointedly warned Moscow it could face new sanctions within weeks if it failed to go along. At the time, he said he would carry the same message to Putin if the two crossed paths in France.
Prior to flying to Brussels for the G-7, Obama was also in Warsaw, Poland.
