Kerry arrived on East Coast to undergo treatment for leg at

A US military C-17 transport aircraft that usually carries at least 100 troops flew to Geneva Airport to pick up Secretary of State John Kerry and flew him to Boston where he'll be treated for a broken leg.

The Air Force plane touched down in Switzerland on Monday after taking off from a US base in Ramstein, Germany, and then headed to Massachusetts after collecting the 71-year-old politician.

Kerry tweeted out 'big thanks' to his well-wishers and said he looked forward to getting his leg set and getting back to work at the State Department.

The C-17 was carrying 'additional military medical personnel in keeping with standard practice', according to Kerry spokesman John Kirby, the Washington Post reported.

The planes, which are manufactured by Boeing, serve as the Air Force’s 'primary strategic lift aircraft for global transport of troops and equipment', according to Military.com.

C-17s 'can perform tactical airlift and airdrop missions and can transport litters and ambulatory patients during aeromedical evacuations when required.'

Kerry, who is set to arrive in Boston on Monday evening and be admitted to Massachusetts General Hospital, said he was 'particularly grateful to the remarkable police and medical teams in Geneva and Scionzier', adding the staffs are full of 'true professionals'.

The former Presidential candidate fell off his bike Sunday morning after striking a curb near Scionzier, a French Alpine village, and fractured his right femur in the 9.40am incident.

He was 'stable and never lost consciousness' and taken by helicopter to Geneva's General Hospital, HUG, about 30 miles away.

There were plans to fly Kerry home on Sunday, but he ended up staying overnight, according to the Post and Courier.

Kirby said: 'It was sensible for him to remain in the hospital for observation overnight for purely precautionary measures.

'The secretary continues to be in great spirits and active.

'He has done a range of phone calls including with the president.'

The doctor who will treat Kerry in Boston, Dennis Burke, previously operated on his right hip.

As a result of the accident, Kerry canceled the rest of a four-nation trip that included an international conference on combating the Islamic State group.

After Kerry's Sunday morning accident, paramedics who were on the scene with his motorcade provided him immediate attention.

They quickly decided to order the ten-minute-long helicopter transport to Geneva.

Kerry's cycling rides have become a regular occurrence on his trips and he often takes his bike with him,

During discussions in late March and early April between world powers and Iran, he took several bike trips during breaks.

Those talks were in Lausanne, Switzerland, and led to a framework agreement.

Sunday's accident came as the secretary wanted to ride along a small part of the Tour de France that would have taken him into an Alpine pass.

At the time of the crash he was riding on flat ground near the town, officials told AFP.

Kerry had been in Geneva for six hours of meetings with Iranian Foreign Minister Mohammad Javad Zarif on Saturday as the sides now work to seal a comprehensive accord by June 30.

Zarif and his officials left Saturday evening, though an extra day had been built into the secretary's trip in case talks needed to go longer.

Kerry regrets not being able to make the rest of his scheduled stops, Kirby said.

The top US diplomat had planned to travel later Sunday to Madrid for meetings with Spain's king and prime minister, before spending two days in Paris for an international gathering to combat extremist group ISIS.

He will participate in the Paris conference remotely, Kirby said.
