Residents reached by telephone in the town of Xarardheere, a pirate haven in central Somalia, said that the pirates were sending small boats with additional supplies, pirates, and weapons to the hostage scene. The Associated Press reported that the pirates were sending larger ships—including previously hijacked ships with hostages still aboard—to serve as shields for the small, enclosed lifeboat that now holds four Somali pirates and their American captive, Capt. Richard Phillips.
I think the pirates have miscalculated, and I believe they should cut their losses while they can. I don't think they realize which nation they're dealing with in this encounter.
