Gonomukti O Jatiya Sampad Rokkha Sammilita Andolan, a platform of several left-leaning parties to save country's national resources, also demanded Niko's trial for Tengratila blowout under the existing laws of the country.

At a press conference at Bangladesh Samajtantrik Dal (BSD) office in the city, the leaders of the organisation demanded exemplary punishment to corrupt ministers, bureaucrats and other associates of Niko and suspension of its activities.

They also demanded compensation from Niko for the victims and immediate steps to douse the fire at Tengratila gas field.

" We visited Tengratila on June 27 and found severe damage of properties and environment," said the leaders.

"The government has identified only 267 affected families, but we found more than thousand families who were affected seriously," they added.

BSD leader Khalequzzaman, Workers' Party General Secretary Saiful Haque, Shamsuzzaman Milon, Journalist Nazrul Islam Renu, and Abdullah Sarkar were present at the press conference.

Jatiya Mukti Council, another left-leaning organisation, also made similar demands including cancellation of all PSCs and expulsion of Niko.

In a joint statement, council President Badruddin Umar and General Secretary Fayzul Haqim demanded adequate compensation from Niko for the victims.

Like previous Awami League government, the present alliance government has also failed to get compensation from foreign multinational oil companies, they alleged.
