一份新报告说，尽管有世界各国海军的努力，但是索马里海盗对国际航运而言仍是一个威胁。
国际海事局星期一表示，在一月到九月，全世界报导的将近300起海盗事件中，索马里海盗发起的袭击事件占44%。
星期一公布的国际海事局的报告还表示，索马里海盗还对同期发生的39起劫持船只事件中的35起负责。
在索马里和也门之间的亚丁湾海盗袭击激增，使得许多国家派遣海军部队到这个海域。
报告说，海军的存在有助于控制海盗，但也指出索马里海盗已经扩大了在印度洋北部和红海南部袭击船只的范围。
国际海事局说，海盗行动涵盖的海域过于辽阔，海军并不能实际覆盖这么广大的地区。
A new report says Somali pirates remain a threat to international shipping despite the efforts of the world's navies.
The International Maritime Bureau said Monday that Somali pirates carried out 44 percent of the nearly 300 piracy incidents reported worldwide between January and September.
The IMB report, released Monday, also said Somali pirates were responsible for 35 of the 39 hijackings during that same period.
A surge in pirate attacks in the Gulf of Aden, between Somalia and Yemen, prompted many countries to send naval forces to the area.
The report said the naval presence has helped control piracy, but noted that Somali pirates have expanded their range to attack ships in the northern Indian Ocean and the southern Red Sea.
The IMB says the area where the pirates operate is so vast that the navies cannot realistically cover it.
