KATHMANDU: Deputy Prime Minister and Minister for Foreign Affairs Sujata Koirala on Tuesday said the government is committed to arresting the killers of media baron Jamim Shah. After meeting Shah's bereaved family at their residence in Panipokhari, DPM Koirala said the security forces have launched a manhunt to arrest the killers. Shah was shot dead in Lazimpat on Sunday. The killing of a prestigious citizen in broad daylight has raised a question mark in the nation's security, she said, adding that security personnel deployed in the area during the time of the killing should also be brought under investigation and actions should be taken against them.
