Gunmen kill 5 in attack on Shiites in southwestern Pakistan

Pakistani police say gunmen have ambushed a car carrying minority Shiite Muslims in the southwestern city of Quetta, killing four of them and a passer-by.

Local police chief Hidayat Ullah says two other passers-by were also wounded in Monday's attack in Quetta, the capital of Baluchistan province.

No one immediately claimed responsibility for the attack, but Sunni extremists regularly target Shiites and have staged previous such attacks in Baluchistan and elsewhere in Pakistan.

Last Thursday, a suicide bomber targeted a Shiite shrine packed with worshippers in the remote village of Jhal Masgi in Baluchistan, killing 24 people.

Pakistan's Islamic State affiliate claimed responsibility for that attack. IS and other Sunni extremist groups view Shiites as apostates and frequently target them in deadly attacks.
