PERTH, Australia (AP) - China's official news agency says a Chinese ship that is part of the multinational search effort looking for the missing Malaysia Airlines plane has detected a "pulse signal" in southern Indian Ocean waters.
The report says a black box detector deployed by the vessel picked up a signal at 37.5Hz per second Saturday at around 25 degrees south latitude and 101 degrees east longitude.
The report said it was not established whether that the signal was related to the missing jet.
The Australian government agency coordinating the search would not immediately comment on the report.
Military and civilian planes, ships with deep-sea searching equipment and a British nuclear submarine are scouring a remote patch of the southern Indian Ocean off Australia's west coast in an increasingly urgent hunt for debris and the flight recorders that hold vital information about Malaysia Airlines Flight 370's last hours.
