Afghan officials say a suicide car bomb attack near the Russian Embassy in the capital Kabul has killed at least six people, including four women and a child.
Health ministry director Mohammad Ismail Kawasi told VOA at least 28 other people were wounded in the blast Wednesday.
Russian foreign ministry officials say there were no injuries among Russian staff and that the embassy in Kabul will increase security.
Local media reports say the target of the attack was a minibus carrying production of staff of a private television channel.
Pictures from the scene posted on social media show black smoke billowing into the sky.
There are no immediate claims of responsibility for the bombing, though initial suspicion fell on the Taliban insurgency. The militant group has claimed such attacks in Kabul and elsewhere in Afghanistan in recent days. All of the victims of Wednesday's violence are said to be Afghan civilians.
Meanwhile, the U.S. embassy in Afghanistan said in a statement on Wednesday that it has received reports that militants were planning to attack an unknown hotel or guesthouse frequented by the international community in the Shar-e-Now area of Kabul this month.
It said there is no further information regarding the timing, target, location, or method of any planned attacks.
The embassy warned U.S. citizens that the security situation in Afghanistan is extremely unstable.
