CAIRO — Egypt's government has disrupted Internet service and deployed an elite special operations counter-terrorism force hours before anti-government protesters expect a new wave of mass rallies to begin.The police counter-terrorism force is rarely seen on the streets. Its officers took up positions early Friday in strategic locations in Cairo, including central Tahrir Square, site of the biggest demonstrations earlier this week.This week's grass-roots protest movement in Egypt has been fueled by traffic on social networking sites, but Internet outages have become widespread. A major service provider for Egypt, Italy-based Seabone, reported early Friday that there was no Internet traffic going into or out of the country after 12:30 a.m. local time.
