Malaysia flight MH370: Search ships to verify signals

A UK ship with sophisticated detection equipment, HMS Echo, has arrived in an area where a Chinese vessel searching for the missing Malaysian plane has twice detected a pulse signal, according to a news agency.
Australia's HMS Shield is first investigating a possible third signal elsewhere in the massive search zone. None have been confirmed as coming from the flight recorders of MH370.
Meanwhile families of the missing passengers have attended a prayer service in Kuala Lumpur. The plane disappeared four weeks ago with 239 people on board.
Investigators believe it crashed in the Indian Ocean although no confirmed debris has been found.
Australian co-ordinators said on Sunday that new analysis of satellite data meant efforts would now focus on the southern part of the search zone, near where China's vessel is located.
