Pakistan's interior minister is visiting Iran to discuss regional security, stability and other developments, the Pakistani foreign office said on Wednesday.

Mohsin Naqvi, previously involved in mediation efforts between Iran and the US, is known to be close to the powerful head of the Pakistani army, Asim Munir.

Iranian state news agency IRNA reported late on Tuesday that Naqvi met with Iranian President Masoud Pezeshkian, Foreign Minister Abbas Araghchi and Interior Minister Eskandar Momeni.

"He is discussing bilateral relations, security, regional security and stability, and constructive engagement amongst the parties in the region and regional developments," Pakistani foreign ministry spokesman Tahir Andrabi told reporters in Islamabad.

The Iranian government's website said Naqvi conveyed to Pezeshkian "a message from the Pakistani prime minister and the chief of the army", without specifying its content.
