Egypt clashes claim the life of an American Opponents of Egypt's Islamist President Mohammed Morsi protest outside the defence ministry, in Cairo, Egypt, on Friday. AN American was among two people killed in Egypt's second city of Alexandria on Friday as clashes erupted during rival demonstrations for and against Islamist President Mohamed Morsi a year after his election. The US citizen, a 21-year-old who reportedly worked for an American cultural centre in Alexandria, was killed as he took photographs of a demonstration, officials said. An official at the US embassy in Cairo told AFP: "We have heard of reports of the death of a US citizen. We are seeking to confirm. Clashes also erupted in the Nile Delta provinces of Daqahliya and Beheira, security officials said, adding that at least 130 people were injured nationwide. Tens of thousands of backers and opponents of Egypt's Islamist president held competing rallies in the capital Friday. The offices of the Freedom and Justice Party, the political arm of Morsi's Muslim Brotherhood, were torched in Alexandria and at Aga in Daqahliya, and FJP offices were stormed in Beheira. Morsi, 62, has been accused by opponents of failing the 2011 revolution that brought him to power and of ignoring nearly half of the electorate of around 50 million that did not vote for him last year. Egyptian protesters wave their hands and hold national flags during anti-President Mohammed Morsi demonstration in Tahrir Square on Friday. Friday's pro-Morsi demonstrations were seen as a pre-emptive strike by the regime two days before the opposition rallies. In Cairo, tens of thousands of Islamists gathered under the slogan "legitimacy is a red line," referring to Morsi's insistence he has a popular mandate. Opponents also gathered in Alexandria, Mansura and the canal city of Port Said. New clashes erupted between the two sides in Egypt's second largest city, Alexandria, in a prelude to massive nationwide protests planned by the opposition this weekend demanding Mohammed Morsi's removal. It's not about sacking Morsi himself. Our demands are clear: bread, freedom, social justice and human dignity," one Tahrir protester told AFP. We urge all parties to refrain from violence and express their views peacefully. And political leaders have the responsibility of taking steps to ensure that groups do not resort to violence," US State Department spokesman Patrick Ventrell said.
