World pressure on the Syrian regime escalated Wednesday as Turkey announced tough economic sanctions and a leading U.N. body announced a Friday meeting on the human rights situation. In Saudi Arabia, the Organization of Islamic Conference, a worldwide alliance of Muslim nations, met on Wednesday to discuss the bloodshed in Syria, whose government has been widely condemned for its fierce crackdown against protesters. "Collective punishment methods, besieging cities, bombing mosques, using excessive violence against peaceful demonstrators and killing tens of people every day pointing weapons to their own people with army units following armed gangs such as shabiha are the manifestations of the Syrian administration's lack of understanding of legitimacy," said Turkish Foreign Minister Davutoglu, who announced a series of sanctions against Syria. Turkey plans to stop selling and providing weaponry to the Syrian army. It also will prevent the transfer of munitions from third countries to Syria via Turkey, Davutoglu said.
