Swine flu fears have prompted three US war ships to stay offshore in Guam where they were due to be refuelled and restocked.
This came after some sailors exhibited flu-like symptoms, but the US Navy says it has not been determined if anyone on the vessels carries the H1N1 virus.
As a precaution, the ships stayed offshore and supplies and fuel were transported to them via other vessels.
The ships were on their way back to San Diego from deployment in the Gulf.
