Tahir Khan (Expert on Afghan Affairs): The situation in Afghanistan has worsened due to wrong policies adopted by the US and its allies. That is the main reason of the destabilization of the whole region. Pakistan has been the worst affected country due to war in neighboring Afghanistan. A large number of Afghan refugees are living in Pakistan, putting strain on economy and resources of our country. Pakistan has now decided that it will allow more refugees only after scrutiny of their documents. It is unfortunate that world community is not recognizing Taliban government in Afghanistan. Russia is concerned about the presence of IS and other militant groups still present in Afghanistan. It fears the fallout on Central Asian States that lie in its backyard.
