Three engineers from a Turkish company have been killed in a suicide bombing in eastern Afghanistan, according to officials.
The spokesman for the governor in Nangharhar province said the attack took place on Monday morning when the Turkish workers were travelling to work in the district of Behsud.
Ahmad Zia Abdulzai said the bomber drove a motorcycle and the explosion killed three engineers and wounded a fourth.
The team was working on a construction project in Behsud.
"Turkish engineers were entering the facility by a car when the rickshaw loaded with explosives blew up," Fazel Ahmad Shirzad, provincial police chief, said.
No one claimed responsibility for the attack and officials at the Turkish embassy in Kabul could not immediately be reached for comment.
