Photo taken on March 28, 2018 shows Michael Rakowitz's sculpture "The Invisible Enemy Should Not Exist" on the Fourth Plinth in London's Trafalgar Square, Britain. The sculpture made from 10,500 empty Iraqi date syrup cans, is a replica of Lamassu, a winged bull and protective deity, that stood at the entrance to the Nergal Gate of Nineveh from 700 BC until it was destroyed by ISIS in 2015. It is the 12th work to appear on the Fourth Plinth since the commissioning programme began in 1998, and will be on the plinth until March 2020. (Xinhua/Stephen Chung)
