In news from Egypt, opposition politician Ayman Nour said Monday he wanted to run for president again next year and would challenge a rule that bars him from entering the race. Nour is one of Egypt’s best-known dissidents. In 2005 he challenged Hosni Mubarak for president but came in a distant second. Soon after the vote, Nour was sentenced to five years in prison on charges of allegedly forging some of the signatures required to register his political party. Egyptian law bans Nour from any political office for at least five years after the end of his original jail term.
