The 20-month-old violence in Syria sees no end yet despite continuous international mediation efforts, as blasts and shootings again devastated the capital of the conflict-torn country. Twin blasts struck a district of Damascus earlier on Friday, injuring 16 people. The explosions were followed by intense shooting from security forces. At the same time, Syrian warplanes were seen hovering over the capital, as jet fighters have reportedly broken the sound barrier twice. Blasts became daily occurrences in the capital as armed rebels intensified their attacks in the hope of wobbling the government's tight grip on Damascus. Also on Friday, world powers started a new round of debate over the Syria issue. Russian Deputy Foreign Minister Gennady Gatilov accused that the Western attempts to press new Syrian leaders from outside contradicted the Geneva agreement reached by all world powers. According to the Geneva communique, a transitional governing body must be formed on the basis of mutual agreement between the government and the opposition.
