BERLIN - Germany on Wednesday accused Russia and Iran of carrying some responsibility for a suspected chemical weapons attack by Syrian President Bashar Assad's forces that killed scores of people in a rebel-held area. 'The federal government sees responsibility lying with Russia and Iran as allies of the Assad regime,' a German government spokeswoman told a regular news conference in Berlin. 'We are convinced that without their massive military support the regime would have long ago had to agree to serious negotiations about a political solution,' she added.
