New Delhi, Aug 4 - Opposition parties walked out of the Lok Sabha Tuesday on the issue of the Pakistani Supreme Court indefinitely adjourning the case against the release from house arrest of Jamaat-ud Daawa (JuD) chief Hafiz Saeed, who India says masterminded the 26/11 Mumbai terror attacks.

As the house assembled at 1 p.m. after a 45-minute adjournment caused by the same issue, Leader of Opposition L.K. Advani of the Bharatiya Janata Party (BJP) demanded a clarification from Prime Minister Manmohan Singh or External Affairs Minister S.M. Krishna on what he termed their contradictory statements on Pakistan.

Advani cited Krishna's interview in a leading newspaper in which he said 'all talks between the foreign secretaries of the two countries are futile' till Pakistan takes credible action against the perpetrators of the Mumbai terror attacks.

'The prime minister had earlier stated that foreign secretaries of India and Pakistan would meet any number of times till it is necessary,' Advani then pointed out.

Demanding an explanation on the statements, Advani said: 'Either the prime minister or the foreign minister should explain this contradiction.'

After Advani, Congress MP from Maharashtra Sanjay Nirupam spoke on the issue, demanding that Saeed 'must be brought to book and punished. He must be arrested again.'

On Monday, Pakistan's Supreme Court indefinitely adjourned the hearing of petitions challenging Saeed's release from house arrest in June, effectively setting him free.

Janata Dal-United (JD-U) leader Sharad Yadav said: 'Terrorism and dialogue can not go together. Talks are meaningless if Saeed is not brought to book'.

According to former railways minister and Rashtriya Janata Dal (RJD) chief Lalu Prasad,'everyone in the country knows that he is the mastermind.
