The blasts come just weeks after two of Saudi Arabia's biggest oil installations were hit, wiping out five per cent of global production.
Oil prices surged more than two per cent Friday after an Iranian tanker was hit by suspected missile strikes near Saudi Arabia, sparking fresh supply concerns with tensions already high after last month's attacks on two Saudi crude facilities.
The National Iranian Tanker Company, which owns the ship, said the hull of the Sabiti was hit by two separate explosions off the Saudi coast, saying they were "probably caused by missile strikes".
The news sent Brent surging 2.3 per cent to $60.46, while West Texas Intermediate jumped 2.1 per cent to $54.69. Prices had already been rising on growing hopes for a breakthrough in the China-US trade talks.
