ISLAMABAD- A Pakistan’s top security adviser today told the visiting U.S. regional envoy that the security forces were targeting all armed groups in the North Waziristan tribal region.

The comments came days after the U.S. commander of NATO-led forces in Afghanistan, General Joseph Dunford, said he has reservations about the overall effectiveness of the army operations in North Waziristan.

Dunford said Pakistani forces have had some success against the Pakistani Taliban and the IMU [Islamic Movement of Uzbekistan] in North Waziristan but that they certainly have not had the effect against the Haqqani Network and others that Washington would want to have seen.

However, Pakistani Adviser to the Prime Minister on National Security and Foreign Affairs, Mr. Sartaj Aziz told U.S. Special Representative for Afghanistan and Pakistan, James Dobbins, in Islamabad that Pakistan is taking action again all militants in North Waziristan.

“The Adviser highlighted Pakistan’s monumental effort to address the threat of terrorism and underscored that the military operation was addressing this menace without any discrimination or distinction,” a Foreign Ministry statement quoted Aziz as telling ambassador Dobbins.

Pakistani forces launched major offensive codenamed “Zarb-e-Azb” against local and foreign militants on June 15, 2014 and have killed nearly 450 militants.

“The two sides reiterated their resolve to further deepen the bilateral relationship and strengthen mutual consultations on Afghanistan post-2014 with a view to advancing the shared objectives of peace, stability and economic development in the region and beyond,” the Foreign Ministry said.

Mr Aziz welcomed the solution to the election crisis in Afghanistan and appreciated the efforts of Secretary John Kerry who had contributed to an amicable understanding on election-related issues.

"The Adviser also underlined Pakistan’s support for a peaceful democratic transition, underscoring its vital importance for stability in Afghanistan and the region,” he said and reaffirmed Pakistan’s commitment to a peaceful, stable and united Afghanistan. Dobbins arrived in Pakistan on Monday on a farewell visit after meeting President Hamid Karzai in Kabul. The Adviser took the opportunity to laud Ambassador Dobbins’ efforts for the promotion of stable, cooperative and durable relations between Pakistan and the U.S. during his term as the Special Representative Afghanistan and Pakistan.
