"I... extend deepest gratitude to the leadership of both the countries and invite their delegations to Islamabad on Friday, 10th April 2026, to further negotiate for a conclusive agreement to settle all disputes," he said in a post on X.

Pakistan, which has forged a close relationship with President Donald Trump and is sensitive to developments in neighbouring Iran, emerged as a channel for messaging between Tehran and Washington in recent weeks.

"We earnestly hope, that the 'Islamabad Talks' succeed in achieving sustainable peace and wish to share more good news in coming days," Sharif said.

Both Tehran and Washington said they had agreed to a two-week ceasefire barely an hour before President Donald Trump's deadline to obliterate Iran was set to expire.

The war began when Israel and the United States launched strikes on Iran that killed its supreme leader on February 28, sparking retaliatory attacks from Tehran on Gulf nations and Israel.

Lebanon has also been drawn into the conflict after Iran-backed group Hezbollah launched attacks on Israel, which has since carried out strikes, including on the capital, and launched a ground operation in the south of the country.

Sharif said the ceasefire applied "everywhere", including Lebanon, though Israel later said it did not apply to that country, where it is carrying out aerial and ground operations against Iranian-backed Hezbollah,

The temporary ceasefire came after a down-to-the-wire bid by Pakistan and other mediators to avert Trump's threat to destroy all power plants and bridges across Iran, a move that legal experts said could constitute a war crime.

Turkey and Egypt had also been helping mediate in recent days, while China helped get Iran to the negotiating table, Trump told AFP on Wednesday.

Despite trading missile fire with Iran two years ago and holding an at-times rocky relationship with Washington, Islamabad currently shares warm ties with both capitals.

That helped boost its moderating credentials, burnished by its allyship with heavyweight regional players, including Saudi Arabia and Beijing.

Pakistan is home to the world's second-biggest Shia Muslim population after Iran -- with which it shares a 900-kilometre border -- and represents some Iranian diplomatic interests in Washington where Tehran has no embassy.

The announcement by Trump late on Tuesday represented an abrupt turnaround from his extraordinary warning earlier, and came after mediation efforts by Pakistan's military chief, Field Marshal Asim Munir, and its Prime Minister Sharif.

The eleventh-hour deal was subject to Iran's agreement to pause its blockade of oil and gas supplies through the strait, Trump said. The waterway typically handles about one-fifth of global oil shipments. 

Iran's foreign minister, Abbas Araqchi, said in a statement Tehran would cease counter-attacks and provide safe passage through the waterway, if attacks against it stop.
