Four die in NATO plane crash in Afghanistan KABUL (Reuters) - Four members of NATO's International Security Assistance Force (ISAF) were killed on Saturday when their plane crashed in southern Afghanistan, the coalition said in a statement. ISAF said there was no insurgent activity in the area when the plane went down over the volatile province of Zabul. The province's police chief Rogh Lewanai told Reuters that bad weather caused the plane to crash, in the district of Shahjoi. Zabul, wedged between Kandahar and Ghazni, has seen much violence over recent weeks, including a suicide bomb attack in early April which killed a young U.S. diplomat, several U.S. soldiers and an unnamed U.S. civilian. Dozens of Afghan civilians have also been killed there this month. Reporting by Mirwais Harooni and Amie Ferris-Rotman; Editing by Stephen Powell
