At least five people were killed on Wednesday afternoon in a suicide bombing in Kabul city. 

A security source said the attack took place in front of the presidential palace's administrative affairs office, which is close to the PD2 headquarters and the defense ministry.

The Ministry of Interior (MoI) on Wednesday said it had no evidence that Russian military officers met with Taliban representatives in Uruzgan province recently.  

The statement comes a day after Uruzgan police chief Ghulam Farooq Sangari claimed that eleven Russian military officers, including two generals and two female doctors, met Taliban officials in Uruzgan.
