Aug 17 (Reuters) - A Boeing 777 aircraft operated by

Swiss International Air Lines flying from Tokyo to Zurich made

an emergency landing in Kazakhstan on Saturday due to a medical

incident onboard, followed by issues after the aircraft landed,

the airline said.

The Boeing 777-300ER's nose wheel got caught in the grass

and was stuck, requiring it to be towed back onto the runway,

the airlines said in a statement. The aircraft will be examined

for damage and will be a subject of an investigation.

Swiss confirmed that none of 319 passengers onboard were

injured due to the incident.

"We'll defer to the airline for information about their

fleet and operations," Boeing ( BA ) said in a statement.
