Turkish Prime Minister Recep Tayyip Erdoğan and French President Francois Hollande, who held a meeting hours before the G-20 summit talks on the global economy in St. Petersburg started, agreed that President Bashar al-Assad’s recent chemical weapons attack in Damascus suburb should not go unpunished.

Indian Prime Minister Manmohan Singh has said that whatever action is required in Syria should be under the UN framework, amid growing pressure on US President Barack Obama from his Russian counterpart and other world leaders not to attack the Arab country.

US President Barack Obama arrived in Russia’s Saint Petersburg for the G20 summit, where officials said he will argue his case for military action against the Syrian regime over an alleged chemical weapons attack.
