LONDON - World oil prices sank on Tuesday, with Brent sliding back under the $100 level, after the Norwegian government acted to end an oil workers’ strike which disrupted supplies to the market.

   Brent North Sea crude for delivery in August dived $1.75 to $98.57 per barrel in morning deals in London.

   New York’s main contract, light sweet crude for August shed $1.08 to $84.91 a barrel.

   A resumption of crude production in Norway after the government stepped in to end an offshore workers’ strike was pulling prices down, said Nick Trevethan, senior commodities strategist for ANZ Research.

“After the government stepped in and ordered a settlement to the strike, that’s returned one to two million barrels per day of oil to the market. That’s having a relatively bearish impact on prices right now,” he told AFP.    Authorities intervened just minutes ahead of a threatened lockout of  Norway’s oil production sites, and ended a 16-day strike by hundreds of workers in western Europe’s largest crude exporter.

   “The strike is over,” labour ministry spokesman Jan Richard Kjelstrup told AFP after the last-ditch deal, which had sent North Sea crude prices plunging below the key $100 threshold.
