Beijing: In a rare move, China has shut down a diplomatic district here housing the Indian and American embassies as angry relatives of passengers of the crashed Malaysian jet held overnight protests over the so far futile search to locate the plane. With no breakthrough despite the high profile multi-nation search operation nearly 50 days after Flight MH370 went missing, relatives of the 153 Chinese passengers had a stormy meeting with Malaysia Airlines staff after which they tried to protest in front of the Malaysian embassy located opposite the Indian mission here.
