Japan on Friday commemorated the fifth anniversary of the devastating earthquake and tsunami that left more than 18,000 dead or missing in 2011. The country observed a minute’s silence at 2.46 pm, the time the 9.0-magnitude quake struck. Prime Minister Shinzo Abe and Emperor Akihito offered flowers at a memorial ceremony in Tokyo.

The disaster was followed by anti-nuclear protests, with scores of people unable to return to their homes despite extensive decontamination work.
