At least six employees of the International Committee of the Red Cross (ICRC) have been killed by suspected Isis gunmen in northern Afghanistan.
Another two employees were unaccounted for after Wednesday’s attack in Jowzjan province, bordering Turkmenistan, where a key motorway has come a focus of insurgent attacks against government forces and NGOs.
Rahmatullah Turkistani, the chief of the provincial police, confirmed the attack and said it took place 22 miles west of the provincial capital, of Shibirghan.
No group immediately claimed responsibility, but the officer said militants loyal to Isis, while the Taliban has denied involvement.
Elsewhere in Afghanistan, a suicide bomber blew himself up after being stopped outside a district government headquarters in the Paktia province, killing two civilians and wounding a policeman.
On Tuesday, another suicide bombing struck the entrance to the Afghan Supreme Court in the capital, Kabul, killing at least 20 people and wounding more than 40 more.
Isis is competing with the Afghan Taliban and al-Qaeda in the continuing Islamist insurgency in the country.
Its affiliate in the region is called Wilayat Khorasan and has claimed responsibility for attacks including suicide bombings and mass shootings targeting police, the military, officials, Shia Muslims and civilians.
