Afghan security officials say they've arrested five men suspected of supporting the December 16 massacre at a school in Pakistan where more than 150 people were killed, almost all of the children.
The Afghan officials said on January 17 that all five were arrested in recent weeks near Afghanistan’s eastern border with Pakistan after Islamabad supplied information about them to Kabul.
They said none of the suspects is an Afghan national.
Pakistan's Taliban, the Tehrik-i Taliban (TTP), claimed responsibility for the massacre, described it as revenge for Pakistan's military's offensive in North Waziristan that started in the summer of 2014.
Pakistani intelligence officials said all seven gunmen in the attack were foreigners.
They released the identities of six -- including three Arabs, two Afghans, and one Chechen.
All seven gunmen were killed in a rescue operation by Pakistani special forces.
