British Prime Minister Keir Starmer condemned President Trump's recent threat that a "whole civilisation" would die unless Iran agreed to end the current conflict, calling the threat against Iranian civilians "wrong."

Meanwhile, Pakistan Prime Minister Sharif indicated that diplomatic efforts to resolve the US-Iran conflict remain active, stating that "full effort" is still underway to find a resolution. Pakistan has previously served as an intermediary in regional disputes.

President Trump also issued warnings to China regarding potential weapons transfers to Iran, threatening "big problems" if Beijing supplies air defense systems to Tehran. Reports suggest possible transfers of man-portable air defense systems (MANPADS) to Iran, though these have not been confirmed.

Former Secretary of State Hillary Clinton criticized the current US position on Iran negotiations, stating during an interview that the United States is in a "very weak position" and has "lost the leverage" in negotiations. She urged the administration to bring in new negotiators to handle the diplomatic process.

The tensions come as international observers express concern about the escalating rhetoric between Washington and Tehran. European leaders have largely maintained distance from the conflict, with some calling for diplomatic rather than military solutions to the ongoing dispute.
