A double suicide bombing at a wrestling club in the Afghan capital Kabul has killed at least 20 people and injured 70, officials say.

After a suicide bomber killed four people in the club, a second bomber in a car attacked emergency services responding to the incident.

Two journalists from the Tolo news channel were killed and four others injured by the car bomb.

The attacks happened in a predominantly Shia Muslim district of the city.

In a post on Twitter, Tolo's head, Lotfullah Najafizada, said the outlet had lost two of its best journalists.

The attack has not yet been claimed by any group but so-called Islamic State has carried out similar attacks in the Dasht-e-Barchi district.

The neighbourhood is home to many members of the Hazara minority.

In 2017, Afghanistan was ranked the third most dangerous country in the world for journalists by Reporters without Borders.
