Tom Cruise's two older children have been sent to a summer camp run by the Church of Scientology, reports claim.

Isabella, 14, and Connor, 12, have been staying at the camp in Oregon while Tom films new movie Valkyrie in Berlin.

A source told America's Star magazine: "The summer camp is part of the Scientology's 'get them while they're young' campaign. While they will be enjoying horseback riding, swimming and all kinds of fun activities, some of their day is devoted to Scientology coursework."

Cruise has been joined by wife Katie Holmes and 16-month-old daughter Suri on the set of Valkyrie, which has been slammed as 'Propaganda for Scientology" by Germany's Protestant church.

The War of the Worlds actor adopted Isabella and Connor with ex-wife Nicole Kidman.
