Syrian protesters took to the streets on friday to call for international protection. At least one person was killed in the northwest by army gunfire as protests erupted across the country and in the capital Damascus after the weekly midday Muslim prayers. On the political front, Turkish Prime Minister Recep Tayyip Erdogan launched a blistering attack on Syria, saying President Bashar al-Assad could lose power over his bloody crackdown. Democracy activists called on the United Nations to send international observers to Syria and urged support from Damascus's key ally Russia a day after President Dmitry Medvedev said some protesters were terrorists.
