SFA Urged To Cancel Qatar Match
The Scottish Football Association (SFA) is facing calls to cancel a planned match between Scotland and Qatar on Friday.
MSP Neil Findlay has tabled a motion at Holyrood raising concerns about "the appalling treatment" of construction workers at World Cup venues".
The motion hits out at "a complete lack of health and safety protection on sites" and goes on to criticise "slave contracts".
It says calling off the game at Easter Road would send the "strongest possible message" to the Qatari authorities.
Earlier the Scottish Trades Union Congress (STUC) wrote to the SFA, calling on it to speak out on the "appalling labour abuse" ahead of the Vauxhall International challenge match.
STUC general secretary Grahame Smith said the association should use the opportunity of the game to make representations to the Qatari authorities.
In a letter to SFA chief executive Stewart Regan, he said: "Since the World Cup was awarded to Qatar, workers have been dying there at a rate of around 40 per month.
"If this rate continues, the International Trade Union Confederation's prediction of 4,000 fatalities will prove tragically conservative.
"I urge you and the SFA to speak out and call on Qatar, through whatever channels are available to you, to address urgently the plight of the workers preparing to host the World Cup."
The SFA today stressed its condemnation of any human rights abuses.
It said in a statement: "As noted recently by Amnesty International, it is important that universal reach of football can be used in a positive manner to highlight inequalities and be a force for good.
"It is with this in mind that we welcome Qatar to Easter Road in June as part of their tour of the United Kingdom."
The statement went on: "We are cognisant of disturbing reports on the conditions experienced by migrant workers involved in the building of stadia for the forthcoming FIFA World Cup in 2022.
"For the avoidance of doubt, the Scottish FA condemns any behaviour that compromises human rights and, in conjunction with the Scottish Government, we have already stated our joint offer to provide practical support."
Another girl was airlifted to hospital.
The attack happened on Waverley Bridge.
Opposition parties are criticising the figures.
