Somali pirates attacked the Maersk Alabama today for the second time in seven months and were thwarted by private guards on board the U.S.-flagged ship who fired off guns and a high-decibel noise device, according to AP. A U.S. surveillance plane was monitoring the ship as it continued to its destination on the Kenyan coast, while a pirate said that the captain of a ship hijacked Monday with 28 North Korean crew members on board had died of wounds. Pirates hijacked the Maersk Alabama last April and took ship captain Richard Phillips hostage, holding him at gunpoint in a lifeboat for five days. Navy SEAL sharpshooters freed Phillips while killing three pirates in a daring nighttime attack. Four suspected pirates in a skiff attacked the ship again on Wednesday around 6:30 a.m. local time, firing on the ship with automatic weapons from about 300 yards (meters) away, a statement from the U.S. Fifth Fleet in Bahrain said. An on-board security team repelled the attack by using evasive maneuvers, small-arms fire and a Long Range Acoustic Device, which can beam earsplitting alarm tones, the fleet said. Vice Adm. Bill Gortney of the U.S. Naval Forces Central Command, said the Maersk Alabama had followed the maritime industry"s «best practices» in having a security team on board. «This is a great example of how merchant mariners can take proactive action to prevent being attacked and why we recommend that ships follow industry best practices if they"re in high-risk areas,» Gortney said in a statement.
