The Muslim Brotherhood said on Wednesday (August 14) that Egyptian security forces killed 30 people as they started clearing out Cairo protest camps that have been demanding the reinstatement of deposed Islamist President Mohamed Morsi.
Egypt's health ministry said there have been no deaths so far in the crackdown.
Egyptian security forces earlier started clearing out the two camps.
At Rabaa, security forces fired teargas as police helicopters circled above and army vehicles were stationed nearby.
The state news agency said security forces had started implementing a phased plan to disperse the protesters, which is almost certain to deepen political turmoil in Egypt.
More than 300 people have already died in political violence since the army overthrew Morsi on July 3, including dozens of his supporters killed by security forces in two separate earlier incidents.
