19 protesters reported dead in Tehran

TEHRAN, June 20 (UPI) -- At least 19 people were killed Saturday in clashes between police and protesters in Tehran, hospital sources told CNN.

CNN said there were unconfirmed reports the death toll was much higher, at least 150. Video posted on the Web showed police using nightsticks, water cannon, tear gas and fire hoses, with some footage of protesters who looked like they had been shot.

The massive protests occurred despite a warning Friday from Iran's supreme leader, Ayatollah Ali Khamenei, that opposition presidential candidate Mir Hossein Mousavi and other anti-government leaders could be held liable for any damage done by demonstrators.

Most of the demonstrations since the government proclaimed President Mahmoud Ahmadinejad had defeated Mousavi 2-1 in last week's presidential election have been peaceful. On Saturday, some protesters fought back when police confronted them, witnesses told The New York Times.

Press TV, a government-run broadcaster, reported the government saying 300 police officers had been injured. Brig. Gen. Ahmad-Reza Radan, the acting police chief, told the Fars News Agency police had received about 2,000 complaints from people asking for vigorous action against the protesters.

Khamenei, in a speech during Friday prayers, said Ahmadinejad had won an "overwhelming victory" and banned any further demonstrations.
