Relatives of those killed in a deadly raid on Pakistan's Karachi airport have demanded stern action against the attackers.

The Pakistani authorities are investigating the raid on Karachi's Jinnah International Airport in which 29 people were killed, including all the 10 attackers.

The families of the victims say negotiations with the Tehreek-e-Taliban Pakistan - which claimed responsibility for the attack - are "useless".
