Locals are mourning the death of Tetsu Nakamura, a Japanese doctor renowned for his aid work in Afghanistan. He was fatally shot on Wednesday.
Nakamura headed the nongovernmental organization Peshawar-kai, based in Fukuoka City, western Japan. He spent years helping the people of Afghanistan in many ways, including by building irrigation canals.
Police in the eastern Afghan province of Nangarhar say Nakamura's car was attacked by unidentified gunmen in the provincial capital Jalalabad on Wednesday.
Nakamura was taken to a local hospital, but was later pronounced dead.
Local police say five more people, including the driver and Nakamura's bodyguards, were killed in the attack.
Many people lit candles and mourned for the 73-year-old in Jalalabad on Wednesday.
A farmer in his 40s said Nakamura had for long provided assistance to them to keep their farmland from being flooded. He said he is so sorry to learn of his death.
No one has so far claimed responsibility for the attack. But police say the attack was likely carried out by three or four men who drove themselves to the scene of ambush. They say they likely fled by car.
They say the attack may have been pre-meditated.
