Two Labour MPs in the Bradford area today revealed they have grave doubts about the bombing of Afghanistan.

Marsha Singh and Ann Cryer said they could rebel against Tony Blair's plea for unity if the military attacks continue.

Mr Singh, MP for Bradford West, suggested the public was being misled about the effectiveness of the campaign.

He has already held talks with Foreign Secretary Jack Straw to explain his fears.

Keighley MP Ann Cryer said she wanted to see the Taliban defeated but feared the bombing was "killing the people we are supposed to be helping".

"I hate the Taliban and everything it stands for, especially the way its attitudes towards women have extended into parts of West Yorkshire," said Mrs Cryer. "But I am now reaching the point where I feel we cannot go on as we are doing.

"These smart bombs are supposed to be very clever but they don't seem that smart to me.

"At the moment we are killing women and children. Unless we start taking on the Taliban as a force, it will have to stop. My support cannot go on indefinitely and cannot be taken for granted.

"I just hope there will be a pause very soon to allow some of the aid to get through."

Both MPs said they feared the bombing could create instability in Pakistan.

Mr Singh said: "The longer the bombing goes on, the more civilians will be killed and more resentment will be generated.

"I am concerned about the situation and especially the news that it could go on for years.

"We have not been told what the military impact of this bombing has been, but I have a feeling it may not be proving as successful as our official line may lead us to believe.

"I am confident that our concerns are being listened to - but to what extent I am not sure at this stage."

Last week Otley MP Harold Best became one of 14 Labour MPs to table a motion calling for an end to the bombing.

He said: "I believe the bombing is unnecessary and counter-productive and I have added my voice to those within Parliament who are seeking the cessation of the bombing.

"That would help to bring aid to the people of Afghanistan and would be a major contribution towards winning their hearts and minds."

But other MPs in the district voiced their support for the Government's policy.

Terry Rooney, MP for Bradford North, said there was "no reason" to oppose the action and that he was "very happy" with its conduct.

Shipley MP Chris Leslie said he was confident the action would succeed.

"I agree completely with the Government's position," he said.

"It's going to be a very long process and it will not be free from problems, but if we do not persevere we will continue to suffer from these kind of attacks.

"I have had a lot of correspondence from my constituents and there are strong views on both sides, but the vast majority recognise we need to carry it out in order to protect ourselves.

"There is no chance that Parliament will do anything but stand with the Government on this. Everybody who is rational and reasonable wants to bring these terrorists to justice."
