New clashes have erupted in Egypt in the ongoing uproar over a proposed referendum on a new constitution. On Tuesday, thousands of people took to the streets to protest Egyptian President Mohamed Morsi’s effort to hold the referendum vote later this month after asserting wide-ranging powers protecting him from judicial oversight. Egyptian forces fired tear gas at demonstrators, some of whom broke through police lines to approach the presidential palace. The rally coincided with a one-day strike by eight Egyptian newspapers against what they allege to be restrictions on freedom of speech in the proposed constitution.
