A Kurdish rebel group said it was responsible for a weekend explosion that killed four people in Turkey, including three foreign tourists.

Turkish officials today quickly denied a television report that a suspected terrorist and three others were injured in a bomb explosion, saying instead that a Turkish tourist had been killed in a gas explosion in southern Turkey.
