At least 20 people were killed and 50 injured in Afghanistan’s capital Kabul on Sunday in a suicide bombing and gun battle at vice presidential candidate Amrullah Saleh’s office, the government said in a statement on Monday.

Saleh, a running mate of Afghan president, Ashraf Ghani, was slightly injured in the attack.

Afghan forces killed three militants who entered Saleh’s four-storey office after a suicide bomber blew himself up during rush hour, said the interior ministry.

More than 150 civilians were rescued during the six-hour-long operation, said interior ministry spokesman Nasrat Rahimi.

No militant group has claimed responsibility for the attack that came only hours after Ghani and Saleh, along with more than a dozen Afghan politicians, launched their two-month long election campaign.

Presidential polls are expected to be held on 28 September but the security situation has been deteriorating across the country with the Taliban and Islamic State fighters mounting near-daily attack on Afghan forces, government employees and civilians.
