Nineteen servicemen from different foreign armies participating in a Ukrainian-US exercise have been hospitalized with non-life-threatening problems, Ukraine’s Defense Ministry said on Monday.
About 1,300 troops from 19 countries, including host nation Ukraine, Armenia, Azerbaijan, Britain, Bulgaria, Canada, Denmark, Georgia, Germany, Moldova, Norway, Poland, Romania, Serbia, Sweden, Turkey and the US are participating in Exercise Rapid Trident 2013 which started last Monday.
The soldiers’ medical problems are related to “adaptation to the local climate, general respiratory disease, and slight foot and ligament injuries,” the ministry said in a statement, denying media reports that the servicemen suffered from food poisoning.
