A Taliban suicide bomber killed at least 13 people and left others injured in an attack on the police headquarters in northern Afghanistan on Sunday.
The deadly assault occurred two days after President Ashraf Ghani offered the Taliban a ceasefire.
The insurgents have rebuffed the move, which came at the end of peace talks in Kabul, and as the Taliban meet with the US at separate talks in Qatar.
Sunday’s attack started with a massive blast at the police facility in Pul-i-Khumri, about 250 kilometres (155 miles) north of Kabul.
The explosion was followed up by gunmen storming the police compound, according to Taliban spokesman Zabihullah Mujahid.
In a tweet, he said a suicide bomber had detonated a bomb inside an armoured personnel carrier, “flattening most of the building”.
Interior ministry spokesman Nasrat Rahimi said 13 police officers were killed in the attack, with another 35 wounded.
Eight attackers were also killed, Rahimi said in a statement, adding 20 civilians were wounded.
Faisal Sami, a senator from Baghlan province, put the toll at 12 killed and 60 wounded.
The current round of talks between the Taliban and US peace envoy Zalmay Khalilzad entered the fourth day on Sunday.
