LOS ANGELES – High-tech entrepreneur Elon Musk took the witness stand at his defamation trial on Tuesday, testifying that his inflammatory Twitter message at the center of the case was sent in response to an “unprovoked” insult he received from the man now suing him.

Musk, the billionaire chief executive of electric carmaker Tesla Inc, was the first witness to testify in the lawsuit brought by a British cave diver who gained fame for his leading role in the rescue of 12 boys and their soccer coach from a flooded cave in Thailand last year.
