Two Pakistani media workers shot dead in Karachi in 24 hours

KARACHI, Pakistan (Reuters) - Gunmen in Pakistan shot dead a journalist on Wednesday, police said, less than 24 hours after a technician working for the country's most popular news channel was killed in a similar attack.

It was unclear who was behind the shootings in the southern port city of Karachi, or if they were linked. Police said bullet casings in the attack on the technician matched those from the recent murders of four policemen.
