Thursday, at least four people were killed and 11 others were injured after a roadside bomb hit a bus carrying Afghan government employees in Kabul, according to officials.

Officials said that the bus was carrying government employees, without giving any further details.

No group has yet taken responsibility for the attack. However, the Afghan government has blamed Taliban insurgents for recent attacks targeting government employees, civil society figures and journalists.

The Taliban has denied involvement in the campaign.

This came on the same day the Afghan government, Taliban and key countries, including the US and Russia, gather in Moscow to push for a reduction in violence to propel the Afghan peace process forward.
