New York: Pakistan needs to take all necessary measures to end "rampant police harassment, threats and violence against Afghans living in Pakistan," Human Rights Watch said today in a new report.

According to the organization, incidents of police abuse against Afghans have skyrocketed since the Pakistan Taliban attacked a school in Peshawar, Pakistan in December last year.

Phelim Kine, deputy Asia director at Human Rights Watch said: "The Pakistani police's outrageous mistreatment of Afghans over the past year calls for an immediate government response."

"The Pakistani government should press the police to apprehend perpetrators of atrocities instead of scapegoating the entire Afghan community," he said.

The lastest HRW study found that Afghans in Pakistan have experienced a sharp increase in hostility since the so-called Pakistani Taliban, Tehreek-i-Taliban Pakistan, attacked the school, killing 145 people, including 132 children.

Human Rights Watch said: "Police abuses have prompted fearful Afghans to restrict their movements, leading to economic hardship and curtailing access to education and employment. This oppressive situation has prompted large numbers of Afghans to return to Afghanistan, where they face a widening conflict and continuing insecurity."

"Deteriorating conditions in Afghanistan have already prompted more than 80,000 Afghans to leave their country in 2015 and seek asylum in Europe. Afghans uprooted by police abuses in Pakistan, where many have lived for decades, to return to Afghanistan may well add to the numbers of those seeking refuge in Europe as conditions deteriorate in Afghanistan," the report stated.
