Supporters of Salafist presidential hopeful, Hazem Salah Abu Ismail, said they will have a 'strong response' if authorities do not refute once and for all that his mother was a naturalised US citizen. After leaving Tahrir Square late on Friday, supporters of presidential hopeful, Hazem Salah Abu-Ismail, threatened to escalate their protests against what they describe as a fraudulent political and media campaign against the Salafist candidate. Their demonstrations already saw some chaos and violence. Several thousand pro-Abu-Ismail protesters in Tahrir, the epicentre of the 2011 uprising, had decided to take to the streets on Friday because their Salafist candidate, Abu-Ismail, is in danger of losing his eligibility to run for president. Allegations have surfaced that Abu Ismail's late mother held Egyptian-US dual nationality - a fact that would immediately disqualify him from the presidential elections should it be officially proven. Their demonstration seemed to be far from peaceful as supporters of Abu Ismail reportedly clashed with opponents of the Islamist-dominated constituent assembly, which is set to draft Egypt's new constitution. The anti-assembly protesters didn't have a choice but to stop chanting after Abu-Ismail supporters stormed their podium to call for the implementation of Islamic sharia and distributed posters of Abu-Ismail.
