Wellington  - A tourist from the Czech Republic was airlifted to hospital on Wednesday after being trapped by falling rocks during a guided tour on New Zealand's Fox Glacier, police said.

The man, in his mid-20s, was seriously injured. Three others with him on the tour organised by the Fox Glacier Guiding company escaped injury.

Two Australian brothers died in January when they were buried under tons of falling ice after ignoring warning signs during an independent family visit to the glacier, which is one of the Southern Alps' main tourist attractions. (dpa)
