CAIRO - Soccer fans obstructed roads and a rail line in Egypt's capital on Wednesday to demand swift punishment of rival supporters and policemen blamed for the deaths of 74 people in a stadium disaster last year.A verdict in the case is due at the weekend, when thousands are expected to mark the second anniversary of Egypt's Arab Spring uprising with street protests against the Islamist-led government.The fans, who took a frontline role in the toppling of autocratic leader Hosni Mubarak in 2011, held a silent protest in front of the stock exchange building in central Cairo, disrupted services at a central subway station and blocked a busy road bridge across the Nile.
