In Islamabad, security measures for the US-Iran talks are extremely tight, with blocked roads, a heavy police and military presence, and tight restrictions on movement and activities in the city. Pakistani authorities have turned the capital into a high-security zone to allow for the possible development of negotiations.
However, despite these preparations, it is still uncertain whether the talks will actually take place. Iran has not fully confirmed its participation, and there have been previous cases where the parties have delayed a decision until the last minute or have been reluctant to participate.
As a result, there is a suspicion that the meetings may not take place at all, leaving the situation uncertain until the last moments, writes the BBC.
