The deceased was identified as Mohammad Habib, 60 while Adnan Azhar, 43 was wounded in the firing, rescue officials said. The body was moved to the Abbasi Shaheed Hospital in Karachi.
JI Karachi President Hafiz Naeem ur Rehman arrived at the hospital and said that Habib had gone for a meeting after he was informed of an illegal electricity connection.
He was gunned down as soon as he left the meeting, he said. Rehman alleged that the Kunda mafia had the backing of the PPP.
He demanded immediate notice by the caretaker chief minister and IG Police and to arrest the culprits and their handlers.
He said that the JI would protest if the authorities did not file a first information report of the killing or fabricate the medical examination of the body.
