The high security measures were in place in Islamabad for the arrival of foreign delegations, even as mixed signals emerged from Iran amid intensifying tensions with the United States.
Iran has said it has not yet decided on attending a new round of negotiations with the US, while President Donald Trump has said that a US delegation is set to arrive in the federal capital on Tuesday.
Despite this, security in Islamabad was on high alert on Monday, with the Red Zone sealed and public transport in the twin cities suspended.
