The Taliban sent an email to media, saying it carried out the attack.
UK Foreign Secretary Philip Hammond confirmed in a statement that a British security contractor was among those killed in the attack.
“I can confirm that a British security contractor is among those killed in the attack. His family has been informed and my thoughts are with them at this incredibly difficult time. Consular staff stand ready to provide support,” Hammond said in a statement.
Apart from the British citizen, two Afghan teenage girls were killed in the attack, while another 18 people were injured.
On Thursday, the Taliban carried out an attack on a hotel, killing 14 people, including a number of foreigners.
The Taliban group, formed in the 1990s, seeks to enforce Sharia law in Afghanistan and Pakistan. The group is known for terrorist attacks and multiple human rights atrocities against authorities and civilians in both countries.
