At least seven teachers were killed in a shooting at a school in northwestern Pakistan on Thursday, in an apparent retaliation to an earlier attack in which another teacher was shot dead, Geo TV reported.
Both incidents took place on Thursday in the Parachinar area of Kurram tribal district near the border with Afghanistan, the local television channel said.
It said the motive behind the killings remained unclear, and that the teachers killed in both incidents belong to the country's Shi'ite Muslim minority.
Local police said they were gathering more information and investigating the incident.
