The parents of a U.S. peace activist who was crushed to death by an Israeli bulldozer built by the global machinery giant Caterpillar confronted the company Wednesday for the first time and urged shareholders at its annual meeting to end sales of "weaponised bulldozers to Israel"...institutional investors who have filed a resolution asking for greater corporate accountability from Caterpillar. Activists...say that the company sells machinery to the Israeli army in violation of its corporate accountability pledge and knowing full well that the equipment will be used for the destruction of Palestinian homes and farms...Caterpillar...has said in the past that it bears no responsibility for how its products are used by clients.
