At least 37 people were killed and 30 others injured in sectarian violence in northwest Pakistan’s restive Khyber Pakhtunkhwa province on Saturday, police said.

The clashes between the tribes of Alizai and Bagan in Kurram district bordering Afghanistan took place following Thursday’s attack on a convoy of passenger vans in which 47 people were killed by militants. Gunfire is also continuing in Balishkhel, Khar Kali, Kunj Alizai and Maqbal.
