KABUL, Afghanistan (AP) - An Afghan official says the Taliban have offered to exchange the body of a U.S. Navy sailor for insurgent prisoners, and the top U.S. military official says the U.S. is doing all it can to return "anybody who has been captured or killed."
      
U.S. and NATO officials confirm that two American Navy personnel disappeared Friday in the dangerous eastern province of Logar. There's been no explanation why.
      
In a telephone interview with The Associated Press, a Taliban spokesman says the pair drove into an area under insurgent control. He says one American was killed and another captured after a brief gunfight. The spokesman didn't mention any offers of deals.
      
The visiting chairman of the U.S. Joint Chiefs of Staff, Adm. Mike Mullen, says "there's a tremendous amount of effort going on" to locate the sailors. He says it's a reminder of "the service and sacrifice that so many make."
