British Prime Minister David Cameron's office said Wednesday that he and US President Barack Obama had no doubt Syrian President Bashar al-Assad's regime had used chemical weapons against its own people.
"Both leaders agreed that all the information available confirmed a chemical weapons attack had taken place, noting that even the Iranian President and Syrian regime had conceded this," a Downing Street spokesperson said after the two leaders spoke on the phone Tuesday night.
"They both agreed they were in no doubt that the Assad regime was responsible."
The statement came as UN inspectors set off Wednesday to a site in Damascus of the alleged chemical weapons attacks, a day after suspending their mission due to safety concerns, an AFP photographer said.
The team of arms experts boarded a convoy of six vehicles, the photographer said. It was unclear which site they were intending to visit.
