"Diplomatic efforts for peaceful settlement of the ongoing war in the Middle East are progressing steadily, strongly and powerfully with the potential to lead to substantive results in near future," Shehbaz Sharif said in a post on X.

"To allow diplomacy to run its course, I earnestly request President Trump to extend the deadline for two weeks."

The appeal came hours ahead of a deadline set by Trump to carry out the "complete demolition" of Iran's critical infrastructure, particularly bridges and power plants, if a deal was not reached by midnight GMT.

The US leader ramped up his rhetoric further on Tuesday, warning "a whole civilization will die" if the Islamic republic did not heed the warning.

In his post, Pakistan's Sharif urged Iran to open the Strait of Hormuz -- vital conduit for the world's oil and gas supply -- "for a corresponding period of two weeks as a goodwill gesture."

The Pakistani leader further called on "all warring parties to observe a ceasefire everywhere for two weeks to allow diplomacy to achieve conclusive termination of war, in the interest of long-term peace and stability in the region."

Pakistan has emerged as a channel for messaging between Tehran and Washington, seeking to mediate to prevent the Middle East conflict from escalating further.

Islamabad has said it is ready to host "meaningful talks" between the United States and Iran.
