SNP leader Alex Salmond has urged people to steer clear of unionist rallies after Better Together accused the Yes campaign of turning "sinister".

Labour MP Jim Murphy, a Better Together supporter, was hit by an egg and said he has been threatened with violence during his 100 Towns in 100 Days tour.

Mr Murphy accepted that Mr Salmond has not personally orchestrated the attacks, but the SNP leader has spoken out to urge Yes supporters to ignore the unionists in future.

Mr Salmond said: "I condemn any egg throwing or any intimidation from any side.

"Somebody was convicted, of course, of online threats against me. Somebody thought his car should be a political weapon. There was a woman, a Yes campaigner, assaulted on the streets of Glasgow.

"I don't hold press conferences accusing Mr Murphy of orchestrating these events, because I know that would be ridiculous to do so.

"So let me be absolutely clear to people, if Mr Murphy comes bawling and shouting in a street corner near you any time soon, keep doing your shopping, keep doing what you were doing.

"He's just like the guy with 'The End Is Nigh' round his neck - he'll go away soon."

Mr Murphy said: "I don't mind heckles and, do you know what, I don't even mind people throwing eggs - that's just a dry cleaning bill.

"But what happened after the first televised debate between Alistair Darling and Alex Salmond is that things took a sinister turn.

"Instead of turning up in crowds of people on all sides there was an organised mob of Yes supporters, facilitated through Yes Scotland and local organisations through websites, Facebook and other social media."

The mobs turned over tables, climbed on crates and tried "to attack a photographer because they happened to be English", according to Mr Murphy.

He said he has been called "a traitor, a Quisling, a terrorist and much else that I can't say" and challenged to several street fights.

"I'm not suggesting Mr Salmond has orchestrated this, of course I'm not, but Yes Scotland at a local level have made that happen," he said.

Mr Salmond said Mr Murphy was being "absolutely and utterly ridiculous" and urged people to visit a blog by an Aberdeenshire journalism graduate to see "exactly see what Mr Murphy has been up to".

The Still Raining, Still Dreaming blog said No voters shouted, pointed fingers and threatened to take Yes signs off nationalists at a Better Together rally in Stonehaven, in Aberdeenshire.

Mr Murphy looked on and denied that both sides of the campaign had intimidating supporters, the blog said.
