3 dead after attack in central Japan; suspect with rifle and knife holed up in building

The witness said he asked the suspect why he attacked her, and he replied that he wanted to kill her, NHK said.

The three victims were taken to a nearby hospital, where the woman was later pronounced dead, police said. The two police officers also died, according to NHK. A fourth person who was injured could not be rescued because he was near the suspect, Kyodo News agency reported.

Video on NHK showed police wearing bulletproof vests and carrying shields, with an ambulance nearby. The area is in a quiet farming neighbourhood.

Police described the suspect as a man wearing a camouflage outfit, a hat, a mask and sunglasses, Kyodo News said. City officials urged those in the area to stay home.

No other details, including about the suspect and the motive, were immediately known.

Violent crimes are rare in Japan. It has strict gun control laws and only a handful of gun-related crimes annually. But in recent years, there have been some high-profile cases involving random knifings on subways and arson attacks, and there is growing concern about homemade guns and explosives.
