 Couple Siezed by pirates on delivery voyage. The couple, along with the yacht's skipper Peter Eldridge, were jumped by 14 pirates who boarded off the coast of Tanzania. They were forced to motor towards Somalia but the engine seized and they drifted for a few days until a French warship arrived. The pirates fired on the warship and the pirates ran the yacht aground and took the couple ashore. More from NZ herald here
