US President Barack Obama and Cuban President Raul Castro shook hands on Friday at a summit in Panama, a symbolically charged gesture as the pair seek to restore ties between two Cold War foes.
"At the Summit of the Americas this evening, President Obama and President Castro greeted each other and shook hands," said Bernadette Meehan, National Security Council Spokesperson.
A White House
official said however the pair did not have a substantive conversation. The two are expected to meet on Saturday.
