President Barack Obama and Cuban President Raul Castro have exchanged greetings and handshakes at the opening of the Summit of the Americas in Panama.
It's the first such interaction between the two men in three years, and one of the only times that the leaders of the U.S. and Cuba have spoken to one another in more than a half century.
The moment was captured on video by Telesur, a Venezuelan network. Obama and Castro can be seen greeting each other in a big crowd while U.N. Secretary-General Ban Ki-moon and Cuban Foreign Minister Bruno Rodriguez look on. Obama and Castro shake hands multiple times while nodding and chatting comfortably.
