Afghanistan's Interior Ministry says a powerful explosion set off by a suicide bomber near the parliament building and a police station in Kabul has killed 20 people.
Afghan Deputy Interior Minister Ayub Salangi said in a tweet that 20 people were also injured in the blast, which was also close to the city zoo entrance.
A Kabul police spokesman said the attacker stood in line with people waiting to enter a national police office and most of those killed were civilians. He said two police also died.
The Taliban claimed responsibility for the attack in a tweet.
The explosion is the latest in a string of attacks in Kabul in recent months that have killed and injured dozens of people.
