Three male suicide attackers wearing burqas have attacked a police headquarters close to the Afghan capital Kabul, killing one policeman as concerns rise over security ahead of the presidential election.
The militants were shot dead on Friday when they stormed the police base in Sarobi district, 50km east of Kabul, after another suicide attacker died when he exploded a vehicle bomb outside the entrance.
Taliban insurgents claimed responsibility for the two-hour attack, which occurred in the same district where presidential candidate Abdullah Abdullah's convoy briefly came under gunfire on Wednesday.
"Today at about 6:20am, a suicide bomber driving a minivan detonated himself at the entrance gate of the Sarobi police headquarters," General Mohammad Zahir, Kabul province's police chief, told AFP.
"Three other terrorists clad in women's burqas entered the courtyard of the building and started firing and resisting the police and army forces.
"As a result of the attack, one officer was killed and three others were wounded."
Male militants have previously used the all-enveloping burqa to disguise themselves and evade security checks in Afghanistan, including in a 2012 attack when four French troops were killed.
Taliban spokesman Zabihullah Mujahid said the insurgents, who were ousted from power in 2001, were behind Friday's attack.
"The mujahideen fighters were equipped with heavy and light weapons and suicide vests, and caused heavy casualties to the enemy," he said in an emailed statement.
Sarobi, on the main road between Kabul and Jalalabad city, is a volatile district in a region seen as key to protecting the capital.
Afghanistan goes to the polls on April 5 to select a successor to President Hamid Karzai, as some 55,000 US-led combat troops pull out of the country after 13 years of battling the fierce Taliban insurgency.
