KARACHI: A couple married recently committed suicide by dumping themselves in front of a train here in Karachi on Sunday. The couple belonged to Vihari. Sajid and Sumira solemnized nikkah in court four days ago and shifted to Karachi after that. Police sources said the couple had been receiving death threats from their relatives for some days which scared them to the extent that they preferred death to life. Police found an application seeking legal protection from the baggage of the ill-fated couple which the duo had sent to Vihari police and session judge, sources added.
