Huge rally and protests mark Iran revolution

TEHRAN, Iran — Hundreds of thousands of Iranians massed Thursday in central Tehran to mark the anniversary of the revolution that created the country’s Islamic republic, while a heavy security force fanned out across the city and moved quickly to snuff out opposition counterprotests. Police clashed with protesters in several sites around Tehran, firing tear gas to disperse them and paintballs to mark them for arrest. Dozens of hard-liners with batons and pepper spray attacked the convoy of a senior opposition leader, Mahdi Karroubi, smashing his car windows and forcing him to turn back as he tried to join the protests, his son Hossein Karroubi told The Associated Press.
