LABOUR MPs were warned not to be dragooned into a “senseless” war in Syria yesterday following reports that “at least 50” could rebel in support of military intervention.

Batley & Spen MP Jo Cox, along with Tory MP Andrew Mitchell, called for military action to establish “safe havens” in Syria — a move which could bring British forces into direct confrontation with Russia. She will launch an all-party group on Syria tomorrow.

In a joint article for the Observer, the pair hinted that Britain could seek to enforce no-fly zones, supposedly in order to protect civilians, although the White House insisted just days ago that such zones were “not being considered.” Peace campaigners were quick to point out that no-fly zones would be “tantamount to a bombing campaign.

“This is exactly how the intervention in Libya, which caused 50,000 deaths, began,” retorted Stop the War Coalition national officer Chris Nineham.

“The last thing we need is yet another disastrous war in the Middle East. We would urge every MP to vote against this.”

Prime Minister David Cameron is said to be planning to ask Parliament for permission to authorise air strikes on Syria, despite losing a vote on the issue in 2013 when his proposed target was the Bashar al-Assad government.

Downing Street now insists it would be attacking the Isis terror group instead — although it continues to demand Mr Assad’s removal and has denounced Russian air strikes on Isis positions.

Labour MP Diane Abbott took to Twitter to condemn the growing war clamour in Westminster, reminding MPs that “bombing Syria won’t help refugees and could actually create more.”

Her forthright stance enraged Blairite sect Progress chairman John Woodcock, who accused the shadow secretary of state for international development of being an “internet troll.”

But supporting a bombing campaign would also mean defying the wishes of the broader party membership, Ms Abbott pointed out. Delegates at Labour’s Brighton conference last month passed a motion opposing air strikes on Syria unless they are endorsed by the United Nations.

And CND general secretary Kate Hudson branded the course of action proposed by Mr Mitchell and Ms Cox “senseless.

“All the evidence suggests this would be a further escalation of a disastrous conflict which requires a political solution.”

“Negotiation is the only way forward,” agreed Communist Party international secretary John Foster. “Britain and the US have the power to stop their allies in the Gulf states and Saudi Arabia supplying arms and finance to Isis. Calls to enforce a no-fly zone must be resisted by all opposed to a disastrous extension of the war.”
