BERLIN, April 5 (Reuters) - Germany on Wednesday accused Russia and Iran of carrying some responsibility for a suspected chemical weapons attack by Syrian President Bashar al-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 convinved that without their massive military support the regime would have long ago had to agree to serious negotiations about a political solution," she added.
