Journalists and colleagues of slain TV producer Soumya Vishwanathan on Saturday launched a campaign to protest her killing and bring the culprits to book.

They will submit petitions before Prime Minister Manmohan Singh [Images], Home Minister Shivraj Patil [Images] and Congress president Sonia Gandhi [Images], demanding justice for Soumya. The journalist was shot dead in the wee hours on September 30 while returning home from work.

Soumya's colleagues condoled the death of the young journalist by lighting candles. Former classmates from Kamala Nehru College, teachers, close friends and journalists from different organisations also participated to show their solidarity with her family members.

As part of the campaign, 'Justice for Soumya', an on-line networking forum, has also been launched to mobilise civil support for her.

The journalists also criticised Chief Minister Sheila Dikshit for her comments that 'one should not be adventurous'.

"We have not been able to come to terms with the tragedy of Soumya's death. There is an eerie silence in the newsroom.

We will continue our crusade for her and urge the whole journalist community to support us," said Rahul Kanwal, editor
 of the Headlines Today.

"Her death is not just another story. It is about someone who was one of us," he added.

"Please keep the campaign alive. Let this incident not go down as just another tragic incident," said Vidisha, a journalist and classmate of Soumya.

Senior journalist Jyoti Malhotra demanded that the government should ensure safety of working women.
