Pakistan’s Prime Minister Shehbaz Sharif is traveling to Tehran to attend the funeral of Iran’s late Supreme Leader Ayatollah Ali Khamenei, according to Al Jazeera. Pakistan’s Foreign Ministry spokesperson Tahir Andarabi told reporters that Sharif will visit Iran and Turkey from July 3 to 5. The funeral ceremonies for Khamenei will begin in Tehran on July 4 and conclude with his burial in his hometown of Mashhad on July 9.

Ayatollah Khamenei, aged 86, served as Iran’s Supreme Leader for 36 years and was widely known as a strong critic of the United States. He was reported to have been killed on February 28, during the first day of the U.S.-Israel war against Iran. Iranian parliamentary speaker Mohammad Bagher Ghalibaf has called for a large turnout at the funeral to honor Khamenei’s legacy.

The visit by Pakistan’s prime minister underscores the close diplomatic ties between Islamabad and Tehran, as regional leaders prepare to pay their respects during the multi-day funeral events.
