Eight suspected terrorists including commander of militant organisation Ansar-ul-Sharia were killed in Rangers operation in Karachi last night.

The Rangers staged a joint raid with counter-terrorism officers in the Raees Goth neighbourhood overnight after intelligence information about the presence of militants there, the Rangers' spokesman for Sindh province, Major Qambar Raza, told AFP.
