The United States has said that Afghanistan and Pakistan need to have cooperation to tackle the challenge of Taliban.

“The conclusion that we’ve drawn here is…that the Taliban poses a security threat to both countries, and that the nations of Afghanistan and Pakistan are going to be able to more effectively confront that threat if they’re able to more effectively cooperate,” White House press secretary Josh Earnest told reporters.

“Any sort of decisions about how the continuation of those talks and any sort of agreement that could be produced by those talks about whether or not that’s in the interest of those countries to pursue – those are decisions that will be made by the leaders in those two countries, as it should be.”

This comes amid efforts by Pakistan to bring Afghan Taliban to the negotiation table which is expected to build a trust between Islamabad and Kabul for joint efforts against other militant groups including the Tehreek-i-Taliban Pakistan (TTP).

The militant groups have been fighting to topple governments in Afghanistan and Pakistan with their bloody campaign. They made January one of the deadliest months by carrying out some brutal attacks.

The latest brutality Afghan Taliban committed was a suicide attack on media staff in Kabul which claimed the lives of seven journalists.

On the other side, the Pakistani Taliban known as Tehreek-i-Taliban Pakistan (TTP) have also killed dozens of people in their attacks including one on a university in Khyber Pakhtunkhwa province that left 21 people killed and more than 30 others wounded. Most of the victim’s of last week’s attack on Bach Khan University were university students.
