Two people were killed and 16 others were wounded Monday during clashes in Cairo between supporters and opponents of ousted Egyptian president Mohammed Morsi, news agencies cited state-run media as reporting. The violence broke out when a group of pro-Morsi demonstrators approached Tahrir Square, where opponents of the ousted president have been holding protests, the newspaper al-Ahram reported online. Police fired tear gas to disperse protesters who threw rocks. An online video showed several gunmen opening fire on protesters in Tahrir Square.
