Tonight, more pirate ships are on the move off the coast of Somalia. They're trying to find the lifeboat holding American Richard Phillips, the captain of a U.S. freighter, who was kidnapped Wednesday by four pirates.
The additional pirate ships are headed into a showdown with the U.S. Navy. The pirates say they're bringing with them at least 50 hostages, or human-shields. They'll use them to stop the Navy from firing at them if they try to get Capt. Phillips off the lifeboat and onto one of their ships and then to Somalia.
Former FBI hostage negotiator, Chris Voss, doesn't believe the U.S. Navy will allow the pirates to take Phillips to shore. That's when it could get really ugly.
Do you think the pirates will attempt this bold move?

The latest tactics come hours after Phillips tried a daring escape. Just after midnight, he tried to swim to the USS Bainbridge, an American warship just a few hunderd yards away. But he didn't make it. Within seconds, the pirates fired their AK-47 riffles, jumped into the water and grabbed him. Phillips was not hurt.
He was later seen moving inside the lifeboat.
Tonight another Navy ship, the USS Halyburton, is on the scene and the USS Boxer should arrive Saturday.
Today Phillips wife issued a statement:
"My husband is a strong man and we will remain strong for him," she said.
Meanwhile, the French military attacked another boat today where five people were being held captive. One of the French hostages and two pirates were killed. The four other hostages, including a child, were freed. We'll have all the details on the deadly rescue effort.
