Diplomatic efforts to de-escalate the war between the United States and Iran continued on Thursday despite renewed strikes and regional retaliation, officials and diplomats said.

Pakistan’s foreign ministry said the country would continue its efforts to mediate between the United States and Iran despite the fresh escalation, stressing the need for a negotiated settlement.

“Pakistan remains deeply concerned at the situation in the region marked by recent escalation... we are of the view that diplomacy and dialogue should be the guiding principles for achieving a negotiated settlement of all contentious issues,” foreign ministry spokesman Tahir Andrabi told journalists.

“It is hard to be an optimist in the new exchange of hostilities. We haven’t lost hope, we remain engaged,” Andrabi said.

“Let’s not draw curtains on Pakistan’s mediation approach,” he added.
