Karachi, Jan 16 (Agencies): The Pakistan Government set up a judicial commission to probe into the murder of a prominent journalist, even as the fresh wave of violence and target killings in the city claimed 31 lives.

Pakistan's financial hub has been in the grip of political violence since Wednesday night and as many as 31 persons have been killed so far, most of them activists of the Muttahida Qaumi Movement (MQM) and the Awami National Party (ANP).

Geo television channel reporter Wali Khan Babar was among those killed in the latest violence.

Interior Minister Rehman Malik had to come out of a meeting with some religious leaders on Saturday to pacify protesting journalists, who raised slogans against the Government for failing to arrest the culprits behind the killing of Babar.

Malik announced the formation of the judicial commission and said it would look into violence against the journalists.

He said they were some elements who were trying to scare and silence the media and the Government will not allow this to happen.

The violence has prompted calls from leading political parties and leaders for it to be discussed in the national assembly and for the Government to take concrete measures to stamp out those involved in these target killings.

Main Opposition PML-N party leader Nawaz Sharif at a Press conference asked the Government to convene a National Assembly meeting on the alarming situation in Karachi and demanded severe punishment to the elements responsible for the unrest in the metropolis.

Rehman Malik also met Jamaat Ulema Islam-F Chief Maulana Fazlur Rehman to discuss the increasingly tense law and order situation in Karachi.

Fazl expressed his concern over incidents of target killings in Karachi and called for the immediate arrest of those involved in such crimes.

Both MQM and ANP, whose activists have been killed in the violence, have come out strongly against the killings.

The ANP submitted an adjournment motion against the violence in the Senate saying these killings are destabilising the city.

The MQM also denounced the violence, saying a stable Karachi is in the best interest of the country after one of its former union councilors was shot dead in Orangi Town on Saturday.

Police said more than 30 suspects have been arrested in late night operations in Karachi since Friday.
