The EU has issued a statement calling on Egyptian security forces to show restraint, following reports that at least 30 people were killed in a dawn crackdown on two sit-in camps of supporters of the country’s ousted president Mohamed Morsi.

“The reports of deaths and injuries are extremely worrying,” Michael Mann, a spokesman for EU foreign policy chief Catherine Ashton, said on Wednesday.

“We reiterate that violence won’t lead to any solution and we urge the Egyptian authorities to proceed with utmost restraint.”

Egyptian security forces killed at least 30 people on Wednesday when they cleared a camp of Cairo protesters who were demanding the reinstatement of deposed President Mohamed Morsi, his Muslim Brotherhood movement said. Two members of the Egyptian security forces were shot dead, the state news agency reported.
