An annex of Shafiq’s headquarters in Cairo was torched late on Monday, AFP reported.
“We were inside when they attacked us,” said one campaign staff member of Shafiq, a former prime minister under the ousted regime of Hosni Mubarak. “They set fire to the garage that had General Shafiq’s campaign literature.”
Firefighters later said that the fire was quickly brought under control.
Meanwhile, on Monday several thousand people demonstrated across Egypt to protest against the results of the first round of the presidential election.
Earlier in the day, the Egyptian electoral commission confirmed that the Muslim Brotherhood’s Mohamed Morsi would face Shafiq in the second round of Egypt’s presidential election on June 16 and 17.
Electoral commission chief Faruq Sultan announced the results of the presidential election, saying Morsi had won 5,764,952 votes or 24.77 percent of the ballots cast, while Shafiq garnered 5,505,327 or 23.66 percent of the vote.
