Dozens of foreign workers have been sentenced to flogging and jail for unrest during protests over unpaid wages by Saudi Binladin Group several months ago, reports said on Tuesday.
An unidentified number were sentenced to four months' jail and 300 lashes for destroying public property and inciting unrest, Al-Watan newspaper reported.
Others were jailed for 45 days by the court in Mecca.
Construction sector workers, chiefly at the Binladin Group and another firm Saudi Oger, were left waiting for salaries after a collapse in oil revenues left the kingdom unable to pay private firms it had contracted.
Arab News reported in May that "unpaid workers" had torched several Binladin Group buses in Mecca.
Authorities confirmed at the time that seven buses were burned but did not give the cause.
A Saudi Binladin Group spokesman could not be reached on Tuesday.
The company, which developed landmark buildings in Saudi Arabia, was founded more than 80 years ago by the father of deceased al-Qaeda leader Osama bin Laden.
Binladin Group late last year said it had completed payment to 70,000 laid-off employees.
Workers still with the company would get their back pay as the government settled its arrears, the company said.
Tens of thousands of employees of Saudi Oger, led by Lebanon's Prime Minister Saad Hariri, were also waiting for wages.
The government said in November that it would pay its arrears to private firms by the following month.
But on December 22, Finance Minister Mohammed Aljadaan, after releasing the 2017 national budget, told reporters that money owed to the private sector would be paid "within 60 days".
