"The men, all foreigners, helped support the Dec. 16 assault by the Taliban at the Army Public School and College in the city of Peshawar… The men were arrested in recent weeks near Afghanistan's eastern border with Pakistan," the Associated Press reported citing Afghan officials, who spoke on conditions of anonymity.
The brazen Peshawar attack sparked a wave of outrage across Pakistan. In response to the assault Afghan President Ashraf Ghani pledged solidarity with Islamabad, despite a longstanding rivalry between Pakistan and Afghanistan. He held talks with Pakistani General Raheel Sharif aimed at strengthening mutual collaboration on fighting cross-border terrorism, the Associated Press narrated.
The two countries have long been blaming each other of sheltering extremist groups which sporadically carry out devastating attacks against both Afghanistan and Pakistan. Currently Islamabad is involved into a military campaign aimed at destroying terrorist hideouts in its mountainous tribal regions along the border with Afghanistan.
