A bomb has reportedly exploded near the entrance of Afghanistan's main airport in Kabul.
A police spokesman said that the blast took place near the aviation directorate office outside the airport, reported the BBC.
While the number of casualties has not been confirmed yet, but a local media outlet said that three people had died and 20 injured in the explosion.
The attack comes just three days after gunmen attacked a guesthouse in Kabul where foreigners were staying, killing 14 people.
