The Haqqani network is believed to have safe havens in Pakistan from where they plan and coordinate attacks against the Afghan and US forces.
Senator McCain arrived in Afghanistan today after concluding his visit to Pakistan, leading a delegation of high level US Senators.
In his meeting with the Chief Executive Officer Abdullah Abdullah, Senator McCain said he asked the Pakistani officials to take steps in fight against terrorism, insisting that a good environment has been created to eliminate the menace of terrorism.
Senator McCain further added that the United States will continue to support Afghanistan until terrorism has fully uprooted from the country and the region.
The Haqqani terrorist network is accused of staging numerous cross-border attacks from their base in North Waziristan, including the 19-hour siege at the US Embassy in Kabul in September 2011.
Haqqani network was formed in the late 1970s by Jalaluddin Haqqani. The group is allied with al-Qaida and the Afghan Taliban and cooperates with other terrorist organizations in the region.
The network is considered the most lethal insurgent group targeting the NATO-led coalition security forces and Afghan personnel in Afghanistan.
The US Department of State designated the HQN as a Foreign Terrorist Organization on September 7, 2012.
