Tight security arrangements were in place in Islamabad’s Red Zone on Saturday as a high-level Iranian delegation was in town amid intensifying diplomatic activity around the US-Iran conflict.

Araghchi arrived in Islamabad late on Friday, carrying Tehran’s formal response to proposals conveyed earlier by the US through Pakistan.

The Islamabad police have said that the Red Zone and Extended Red Zone will be “completely closed to all types of traffic” and issued an alternative traffic plan for the public.

Dawn takes a look at some of the scenes from key roads in Islamabad, where security personnel stand guard and barricades are placed as part of stringent security.
