Almost seven weeks have passed since flight MH370 disappeared en route to Beijing.

But last night, they left the hotel en masse and marched to the nearby Malaysian Embassy. They are now refusing to leave the area outside the embassy gates.
Our correspondent Celia Hatton explains what sparked their anger.
