Pakistan's capital remains locked down as uncertainty looms over the U.S.-Iran peace talks expected to be facilitated by Islamabad. Authorities have sealed major roads and restricted traffic to ensure security amidst speculation that high-profile delegations might arrive at any moment.
More than
10,000 security personnel are deployed across the city, which has remained under strict restrictions for over a week.
“We have been told that the talks could be held any day,” said one government official, highlighting the unpredictable nature of the diplomatic effort.
The first round of talks earlier in April resulted in no breakthrough, leading to renewed efforts by Pakistan officials. Currently, significant areas of the city, including the Red Zone, housing key government buildings, are under a strict security cordon, further complicating daily life for Islamabad's residents.
Officials have granted special permissions for vehicles carrying essential goods amidst the lockdown, emphasizing that
“the entry of heavy transport into Islamabad would remain banned until further orders.” The recent security measures have led to public transport suspensions, affecting over
1,000 passengers daily as road closures persist. Amid the confusion, residents have expressed frustration regarding the lack of clarity about the talks:
“Sometimes the government and media say that the delegations are coming, sometimes they say they aren’t,” lamented one passenger manager.
Despite ongoing traffic disruptions and public discontent,
plans for peace talks continue as Pakistan aims to mediate between the warring nations.
