The attack in Logar province outside the capital, Kabul, was the latest to target Afghan security forces following the withdrawal of most foreign combat troops at the end of last year, Reuters reported.
Taliban group immediately claimed the attacks.
In neighboring Pakistan, another Taliban attack on a provincial police headquarters killed at least seven people in the eastern city of Lahore, in what terrorists called a revenge bid for the recent hangings of their colleagues.
In the Afghan assault, the four attackers rushed the gates of the police compound in early afternoon, with one detonating his explosives-filled vest at the main gate and killing one policeman, Logar government spokesman, Din Mohammad Darwish, said.
“Another reached the station's dining hall, killing 21 police and wounding seven when he detonated his vest,” said Abdul Wali Toofan, Logar's deputy police chief. The other two attackers were killed with no further casualties.
Earlier on Tuesday, a bomb attached to a vehicle wounded one person in Kabul, police said, breaking a recent lull in attacks in the Afghan capital.
Kabul had been rocked by a string of bombings by terrorists late last year in the run-up to the withdrawal of most foreign combat troops from Afghanistan after 13 years of war.
“A suspected magnetic bomb attached to a 4-wheel-drive vehicle exploded in the east of the city,” Kabul police chief Abdul Rahman Rahimi said.
One person was wounded in the blast, Rahimi said, but gave no details.
