A statue of a Japanese Akita dog named “Hachiko” wearing a face mask is seen near Shibuya Station Wednesday, April 8, 2020, in Tokyo. Japanese Prime Minister Shinzo Abe declared a state of emergency on Tuesday for Tokyo and six other prefectures to ramp up defenses against the spread of the new coronavirus. Hachiko has waited for his owner University of Tokyo Prof. Eizaburo Ueno at the same place by the station every afternoon, expecting him to return home for nearly 11 years even after Ueno's death at work.

Police said they belonged to a Bangladeshi group blamed for an attack on a Dhaka cafe earlier this month in which 20 hostages, mostly foreigners, were killed and had been planning another large-scale assault.
