A Pakistani teenage couple who tried to elope were murdered with electric shocks in an "honor killing" by family members who were carrying out the orders of an influential tribal council, police said.

The teenagers in the port city of Karachi were said by the Pashtun council of elders, or jirga, to have brought dishonor on the community.

"The innocent souls were tied to a charpai (rope bed) and given electric shocks," said Aman Marwat, the police officer who arrested the two fathers and two uncles and is pursuing some 30 members of the jirga who have gone into hiding.
