Supporters of deposed Egyptian President Mohammed Morsi attend a sit-in demonstration at Nahda Square in the Giza district on August 12, 2013 in Cairo, Egypt. Egyptian security forces threatened to begin a siege of pro-Morsi protest camps in Cairo overnight on August 11, however Egypt's Interior Ministry appeared to have put off plans to crack down on protesters early on August 12. On Monday Egypt's judiciary also extended deposed President Morsi's detention for a further 15 days pending investigation into charges of his collaboration with the Palestinian Hamas movement. Morsi supporters have continued to protest at sites across Cairo over one month after the Egyptian military deposed Egypt's first democratically elected President, Mohammed Morsi, on July 3.
