Maritime threats:
the International Maritime Bureau continues to report the territorial and offshore waters in the Gulf of Aden and Indian Ocean as a region of significant risk for piracy and armed robbery against ships; during 2018, two vessels were attacked compared with five in 2017; Operation Ocean Shield, the NATO naval task force established in 2009 to combat Somali piracy, concluded its operations in December 2016 as a result of the drop in reported incidents over the last few years; additional anti-piracy measures on the part of ship operators, including the use of on-board armed security teams, have reduced piracy incidents in that body of water; Somali pirates tend to be heavily armed with automatic weapons and rocket propelled grenades; the use of "mother ships" from which skiffs can be launched to attack vessels allows these pirates to extend the range of their operations hundreds of nautical miles offshore
