One elephant trampled another to death at an Israeli nature park. Yossi, a 33-year-old, seven-ton bull elephant, charged and killed his herdÂ’s matriarch Monday, a 46-year-old female named Atari, as visitors at the Safari Park near Tel Aviv watched in horror, according to Ha'aretz. "What happened to Yossi, who grew up all his life with Atari, and they always got along?" Yigal Horowitz, a veterinarian at the park, said to Israel Radio. "Here and there were small fights, but they never had a fight like this one."Prob'ly because one's more than enough.
