U.N.'s Zeid cool on Syrian opposition plan to bypass Russian veto

By Tom Miles GENEVA (Reuters) - The top U.N. human rights official repeated his call on Wednesday for a dilution of big powers' United Nations veto in cases of serious war crimes, but he gave little support to Syrian opposition hopes of strong-arming Russia over eastern Aleppo. Russian war planes have bombed rebel-held eastern Aleppo in the past two weeks in support of Syrian and allied ground forces who are besieging about 275,000 civilians. The United Nations says hospitals have been hit and more than 400 people killed.
