Obama met Venezuela's Maduro on sidelines of Panama summit

PANAMA CITY (Reuters) - U.S. President Barack Obama and Venezuelan President Nicolas Maduro met on the sidelines of the Summit of the Americas on Saturday at a moment of high tension between the two countries, officials for both countries said.

Earlier on Saturday Maduro had challenged Obama to discuss his decision to sanction seven Venezuelan officials, which required a U.S. declaration that Venezuela was a national security threat.
