GENEVA (Reuters) - The international community must do more to persuade the Syrian government to negotiate in U.N.-led talks, which were in  great danger , the head of the opposition delegation said after an eighth round ended in failure in Geneva on Thursday. Opposition negotiator Nasr Hariri told a news conference that the government of President Bashar al-Assad hated the talks process and rejected all negotiations, and although there was pressure from its ally Russia,  another state  was putting obstacles in the path of the Geneva talks.
