A Japanese doctor who devoted his career to improving the lives of Afghans has died, after being injured in an attack in eastern Afghanistan.
Gunmen shot Tetsu Nakamura, 73, while he was travelling in a car to monitor a project, officials say.
Five Afghans were also killed in the attack, which happened in the city of Jalalabad.
Dr Nakamura headed a Japanese charity focused on improving irrigation in the country.
In October this year, he was awarded honorary citizenship from the Afghan government for his humanitarian work.
No-one has yet said they carried out the attack and the motive remains unclear.
Japanese Prime Minister Shinzo Abe said he was “shocked” by the death of Dr Nakamura while the US embassy in Kabul condemned the shooting, saying “aid workers are not targets”.
The United Nations Assistance Mission in Afghanistan (UNAMA) expressed its “revulsion” over the killing.
