The eastern city of Jalalabad has been the site of demonstrations today.

The city, in Nangarhar province, was taken over by the Taliban early on Sunday morning without fighting. Its capture meant the group secured key roads connecting Afghanistan with Pakistan.

But on Wednesday people in the area were filmed marching in support of the old Afghan flag, before gunshots were reportedly fired nearby to disperse crowds.

Video footage from the city appears to show protesters replacing a Taliban flag with that of Afghanistan as cheering crowds look on.

The Taliban's newly declared Islamic Emirate of Afghanistan has so far been using a white flag with a black Shahada (statement of faith) on it. The black, red and green tricolour flag used by protesters today is seen to represent the ousted government.

Taliban spokesman Zabihullah Mujahid has said that discussions are taking place on the future national flag, with a decision to be made by the upcoming government.
