Twenty people were killed in a suicide bomb attack at a police headquarters in a busy area of western Kabul.  The ministry confirmed the news with a statement: “as a result of the terrorist attack this afternoon … 20 people were martyred and 29 others were wounded.”

The ambush was the latest in the series of suicide attacks last month in the Afghan Capital. It was seen as Taliban’s reprisal against the western backed government. The attack came just days before renewed efforts to revive a peace process with the Islamist group, reported CBC News.

Initially the interior ministry informed that it was a car bomb, but later investigators found out that the attacker was on foot and detonated himself in a queue of people waiting to enter into the police station. Afghan deputy interior minister Ayub Salangi tweeted that most of the people killed in the bombing were civilian. However, some reports suggest that most of those killed and injured were officers.

“I saw three bodies on the ground and a number of other people wounded, then ambulances arrived and took all the victims away,” Mohammad Ajmal, a witness, informed.

BBC reported that Monday attack was carried out at the entrance of the headquarters of the Afghan National Civil Order Police (ANCOP). The unit plays a counterinsurgency role against the Taliban.

NATO mission condemned the attack. Brig. Gen. Wilson Shoffner, a spokesperson for NATO and the Resolute Support deputy chief of staff for communications said that once again terrorists had attacked a populated area without any regard for innocent people. He said, “This attack on the Afghan police shows the contempt the Taliban have for the rule of law in Afghanistan and for those who commit themselves daily to defending the Afghan people”.

He further stated, “The Taliban have no plan for the development of Afghanistan. Targeting those who defend their fellow Afghans does not advance the cause of peace.”

In yet another attack a Taliban suicide bomber killed dozens of innocent students at a police academy in Kabul last August, reported CBCNews.
