A man jumps off the Tower Bridge in London, United Kingdom, June 1, 2019. Reuters Photographer Alkis Konstantinidis: "I got a call from UK & Ireland Chief Photographer Dylan Martinez. "Welcome to London," he said, and asked me to head to Tower Bridge, where a man had climbed to the top. Access to the bridge was blocked off by the authorities, and a boat of rescuers from the Royal National Lifeboat Institution was on standby, ready to intervene. I made my way through nearby buildings and reached the banks of the Thames, where police were telling onlookers to move back in order to create a "free zone." I had to secure a position where I wouldn't be removed by police but still maintain a clear view. I stood there, eye in the viewfinder, and didn't move for several minutes. Suddenly, we heard a scream, followed by more screams. The man fell into the river. The fall lasted a couple of seconds and a thump echoed as he landed on his back. I didn't expect him to survive that fall with no injuries, but fortunately, as rescuers rushed towards him, he started swimming towards their boat."

The tower is one of the most significant examples of brutalism, an architectural style popular in the 1950s and 1960s, based on crude, block-like forms cast from concrete. "Genex tower is among the most interesting sight. People see it on their way from the airport and it immediately draws their attention," said Vojin Muncin, manager of the Yugotour sightseeing agency which guides tourists around the Serbian capital.
