Shia Muslims 'killed in Pakistan by pro-Taliban groups'

Security is tight in Pakistan ahead of the Day of Ashura, which is the climax of a period of remembrance for Hussein, the grandson of the Prophet Muhammad.

Already this year, hundreds of Shia Muslims have been killed in Pakistan, mostly in the western province of Balochistan.

Pro-Taliban Sunni militants admit carrying out the attacks, to curb what they call the growing regional influence of neighbouring Iran.

Shoabe Hasan reports from the provincial capital, Quetta.
