Afghanistan says it has lodged an official protest with Pakistan after its forces allegedly came under fire along a contested stretch of their border.

The Foreign Ministry says the incident along the eastern frontier took place early Monday at the same location where a firefight between Afghan and Pakistani forces killed an Afghan border policeman and wounded two Pakistani soldiers last week.

During that incident, a border gate built by Pakistan was damaged in the fighting and Afghanistan had warned Pakistan not to repair it.

The Afghan foreign ministry said no one was wounded in Monday's incident.

Ties between the two neighbors are severely strained, and the mountainous region where the incident took place has seen acrimonious exchanges of fire between the two sides over the demarcation of their border.
