Somali piracy has been a persistent issue off the coast of Somalia. Armed Somali pirates monitor ships and launch attacks to hijack them. When pirates are captured, they are often sent to prisons in Kenya to face prosecution. International naval forces patrol the waters to combat piracy, but competing interests between countries may undermine cooperation. The UN has called for more countries to help Kenya prosecute pirates. Somali piracy has escalated in recent months, with more ships being hijacked, threatening international shipping routes.
