Tens of thousands of protesters poured out onto Egyptian streets after Friday’s midday prayers, prompting the government to impose a curfew from 6 p.m. to 7 a.m. local time. Military vehicles have also been sent down into the streets to quell massive protests demanding an end to the government of President Hosni Mubarak. Meanwhile, reformist leader Mohamed ElBaradei, a Nobel Peace laureate and the UN’s former chief nuclear watchdog, returned home to Egypt to support the demonstrations, but was placed under house arrest by Egyptian authorities. Authorities have also shut down Internet access, as well as mobile phone and text messaging services throughout the country. Seven people have so far been killed in the demonstrations.
