Kabul, Oct 9 (TIWN) A suicide bomber has targeted a mosque in Afghanistan's Kunduz city during Friday prayers, killing at least 50 people, officials said.

More than 100 people were injured in the blast in the northern city.  No group has said it was behind the attack, but Sunni Muslim extremists, including a local Islamic State group, have targeted the Shia community.  They consider Shia Muslims to be heretics.  IS-K, the Afghan regional affiliate of the Islamic State group that is violently opposed to the governing Taliban, has carried out several bombings recently, largely in the east of the country.
