MOSCOW, June 24 (RIA Novosti) - The Iranian opposition has called for another round of protests on Wednesday night in the wake of the government's refusal to review the disputed results of Friday's presidential election, Al Jazeera news agency reported.

The Guardian Council, Iran's highest legislative body, said on Tuesday it would not annul the results of the presidential vote and President Mahmoud Ahmadinejad and his new Cabinet will be sworn in between July 26 and August 19.

At least 19 protesters were reported killed and hundreds arrested over the weekend following street protests in Tehran over alleged ballot fraud following the landslide reelection of the hardline Ahmadinejad on June 12.

Official results gave the incumbent 63% of the vote, with reformist challenger Mir Hossein Mousavi getting 34%.

Iranian Foreign Minister Manouchehr Mottaki warned Europe and the United States on Sunday against meddling in Iran's domestic issues.
