Obama expresses concern at Egypt violence

US President Barack Obama on Saturday expressed concern about political clashes in Egypt and called on President Mohamed Morsi to be more "constructive" in moving the country forward. "We are all looking at the situation there with concern," Obama said in South Africa, adding that the US government had taken steps to ensure the safety of its embassy, consulates and diplomats in Egypt. "We would urge all parties to make sure they are not engaging in violence and that police and military are showing appropriate restraint," said Obama. The US leader also asked Islamist president Morsi to have a more "constructive conversation" to improve the political situation in the country. Egypt was braced for nationwide protests against Morsi on Sunday to mark the anniversary of his turbulent first year in office after violence at rival demonstrations killed three people, including an American.
