A six-member delegation of the National Assembly and Senate returned to Pakistan in protest after refusing a body scan at the Dulles International Airport, located 40 kilometres west of Washington, Geo news exclusively reported on Saturday.

Talking to the channel, head of the delegation Senator Abbas Khan Afridi said they were asked for a body-scan but they refused, as they considered it an insult to parliamentarians of a sovereign country.

He said they were informed before their arrival in the US that they would not face any such discrimination during their visit.

The delegation had reached the US on February 28 for a 15-day visit.
