A U.S. Senate delegation paid a rare visit Sunday to a tribal region along the Afghanistan border that has long been considered a stronghold of al-Qaida, the Taliban and other insurgents, according to ABC News.

The delegation led by Sen. John McCain, R-Ariz. and chairman of the Armed Services Committee, visited the North Waziristan tribal region, a statement from Pakistan's Foreign Office said. McCain posted pictures on his Twitter account of the delegation visiting Pakistani helicopter pilots at an air base in Miram Shah.

"We look forward to closer relations and resolving the differences we have," McCain told Pakistan's state-run TV after meeting with army chief Gen. Raheel Sharif and Sartaj Aziz, the prime minister's top foreign affairs adviser.

McCain added that he was "very impressed" with the progress in North Waziristan.

Foreigners are largely banned from the tribal region, where Pakistan has been waging a military offensive to root out insurgents for two years. The U.S. frequently carries out drone strikes in the region targeting Taliban and al-Qaida leaders.
