President Barack Obama after meeting with the Turkish PM Recep Tayip Erdogan in the White House announced that chemical weapons have been used in Syria conflict. Obama said that has seen the evidence however he insisted that it was important to get more reports about the alleged chemical attacks.

BBC reports that it has seen evidence of chemical weapons being used in Syria. BBC correspondent, Ian Pannell has visited the northern Syrian town of Saraqeb. There he had the chance to speak with witnesses and to watch video recordings. People’s accounts prove that a chemical attack took place in the town last month.  In concrete terms, on 29 April a helicopter has dropped poisonous gas canisters all over the town. Doctors at a local hospital reported that eight people have been admitted with breathing problems. The BBC announced that it could not verify the authenticity of the videos.

"Our militaries are constantly sharing information. We have seen evidence of the use of chemical weapons inside Syria," Obama said. "Those chemical weapons inside of Syria also threaten our security over the long term as well as [that of] our allies and friends and neighbours." However, he added that "more specific information" was needed.

US and Turkey both agree that Assad needs to go. Syria should not become an area for terrorist organizations, said Erdogan. The US and Turkey “agreed that chemical weapons should not be used, and all minorities and their rights should be secured," the Turkish prime minister said, though he did not offer specifics about how that might be achieved reports the Associated Press.
