A visitor places flowers at a makeshift memorial during a vigil for victims of a shooting at a gay nightclub in Orlando, Florida the previous day, in front of the United States embassy on June 13, 2016 in Berlin, Germany. Fifty people were killed and at least as many injured during a Latin music event at the Pulse club in the deadliest mass shooting in the United States and the worst terror attack there since 9/11. The American-born gunman had pledged allegiance to ISIS, though officials have yet to find conclusive evidence of his having any direct connection with foreign extremists.
