A senior female Pakistani politician has been shot dead in the southern port city of Karachi.
Zahra Shahid Hussain was the senior vice-president of Pakistan's Movement for Justice Party led by former international cricketer Imran Khan.
She was killed by gunmen on a motorcycle outside her home in the city's up market Defence neighbourhood.
Her murder comes on the eve of a highly-contested partial re-run of last Saturday's general election.
