Vessels are advised to transit with caution and report any suspicious activity to UKMTO.”The maritime security monitor provided no further details and did not say ‌whether the tanker or its crew were safe.The SIBU 1 has been seized in one of the world’s busiest shipping lanes, as the Gulf of Aden feeds into the Red Sea and the Suez Canal, the fastest maritime link between Asia and Europe. Roughly 12 to 15 percent of global trade by value passes through the canal each year, along with about 30 percent of the world’s container traffic.Piracy was rampant off the coast of Somalia in the 2000s and peaked in 2011 before being curbed by international naval deployments and new security measures for commercial shipping.The attack follows a marked resurgence since April in Somali Piracy, which had been largely dormant for more than a decade until this year.
