KOHAT, Pakistan, Dec. 5 -- A car bomb killed at least 20 people Friday at a police checkpoint in northern Pakistan, police said.
At least 80 people were injured, the Pak Tribune reported.
As much as 50 pounds of explosives detonated, Police Inspector Gen. Naveed Khan told Geo News. He said the crater left by the blast suggests that it was not a suicide attack.
An intelligence official said it appeared the bomber had intended to target minority Shia Muslims, but decided to detonate the bomb after being stopped by police in the Orakzai Agency, Dawn reported.
