( CNN ) -- A terrorist group might be planning attacks on oil tankers in the Strait of Malacca , one of the world 's busiest shipping lanes , Singapore 's navy warned Thursday . `` The terrorists ' intent is probably to achieve widespread publicity and showcase that it remains a viable group , '' said an advisory issued by the Singapore Navy Information Fusion Centre ( IFC ) . `` However , this information does not preclude possible attacks on other large vessels with dangerous cargo , '' the advisory said . The IFC recommended that ships strengthen security measures . It did not name any groups or indicate how the tip was obtained . Located between Indonesia , Malaysia and Singapore , the Strait of Malacca links the Indian Ocean to the South China Sea and Pacific Ocean and is the shortest sea route between Persian Gulf oil suppliers and Asian markets , according to the U.S. government 's Energy Information Administration . The agency estimates that more than 15 million barrels of oil are transported through the strait every day . At its narrowest point , the strait is only 1.7 miles wide , which creates a natural bottleneck and makes it vulnerable to terrorist attack . The IFC warned tanker crews to be on the lookout for smaller vehicles -- including dinghies , sampans and speedboats -- which have been used to launch successful attacks on tankers in the past .
