The IMO released Safety of Navigation Circular 229 providing information regarding submarine pipeline operations in the Singapore Strait-Phillip Channel. Mariners are urged to exercise caution when in this area.

To the astonishment of every five year old, IMO professes an interest in maritime safety. [snicker] I'd call 'em retromingent pithecoids, but that's a bit too polite.
