Expressing deep concern over two Indian Sufi clerics who went missing in Pakistan on Thursday, External Affairs Minister Sushma Swaraj on Friday said that she has spoken to the Pakistani authorities about the matter.

"We have taken up this matter with government of Pakistan and requested them for an update on both the Indian nationals in Pakistan," the Union minister said in a series of tweets.

"Indian nationals Syed Asif li Nizami aged 80 years and his nephew Nazim Ali Nizami had gone to Pakistan on March 8, 2017," she said.

"Syed Asif Ali Nizami is the head priest (Sajjadanashin) of Hazrat Nizammuddin Aulia dargah," she said, adding, both are missing after they landed at Karachi airport.

The two priests had gone to Pakistan as part of annual exchanges between Hazrat Nizamuddin and Garib Nawaz who is venerated at Data Darbar Sufi shrine in Lahore.

According to reports, the two priests were last seen together at Data Darbar.
