A powerful blast rocked the diplomatic quarter in the Afghan capital Kabul targeting a Turkish vehicle outside the Iranian diplomatic post.
The explosion was set off by a suicide car bomber who rammed his vehicle into a car belonging to the Turkish embassy in the upscale area.
The attack took place at about 08:00 am local time in which at least one person has been confirmed killed.
"The driver was killed and two others were wounded," General Mohammad Ayoub Salangi, senior interior ministry official, told reporters.
Turkey's ambassador Ismail Aramaz, who is also Nato's Senior Civilian Representative (SCR), is suspected to have been the target of the bombing. Officials confirmed Aramaz was not present in the vehicle when the blast took place.
Preliminary reports suggest a Vehicle-borne Improvised Explosive Device (VBIED) was used in the attack.
The Taliban, which is currently waging a deadly Islamist insurgency against the Afghan administration in the wake of withdrawal of Nato troops, claimed responsibility for the blast.
