John Travolta owns a home on Islesboro off the coast of Maine

Two pet dogs owned by US actor John Travolta have reportedly been killed in an accident at an airport in Maine.

A service vehicle at Bangor International Airport struck the dogs, according to the Bangor Daily News.

The pets were reportedly being walked after getting off an aeroplane carrying members of Travolta's family.

The newspaper said an e-mail to city councillors confirmed the accident. It said the airport was now investigating the incident.

Family tragedy

Last year, Travolta's 16-year-old son Jett died from a seizure disorder while the family were on holiday in the Bahamas.

Two people are due to stand trial in September accused of blackmailing Travolta over details of his son's death.

The case originally went to trial last year but the judge declared a mistrial because of jury misconduct. Travolta had already given evidence on how he tried to save Jett's life.

Since his son's death, the actor has only made rare public appearances - although he flew his private jet to Haiti after January's devastating earthquake to aid the relief effort.

His most recent film was thriller From Paris With Love, which hit UK cinemas in February.
