A senior journalist was shot dead in an attack in Pakistan's port city of Karachi on Wednesday, the media reported.
Aftab Alam was killed when unidentified assailants opened fire at him near his home in North Karachi, Dawn online reported.
Alam was shot in the head in the shooting that took place near Sir Syed market. Deputy Inspector General of Police Feroz Shah said three bullets were recovered from the site.
The Karachi Union of Journalists said Alam's killing posed a question mark over the efficacy of the government and security agencies.
The union has demanded the immediate arrest of killers of both Alam and Arshad Ali Jafri, a media worker, killed on Tuesday in the port city.
Alam was earlier employed with Geo News and was unemployed since a year due to health issues.
Alam was shot hours after senior engineer Arshad Ali Jafri, who was also associated with Geo News, was gunned down in an attack on the channel's van in Karachi's Bahadurabad area.
Police remained clueless about the motive of Tuesday's attack, but investigators said they were sure it was a murder attempt.
The Geo News management called it a 'targeted attack' and said the assault apparently was meant to harass not only the channel's staff but also the entire Pakistani media.
