(CNN) – A Malaysia Airlines passenger jet crashed in eastern Ukraine on Thursday.
"We must and we will find out precisely what happened to this flight. No stone will be left unturned," Malaysian Prime Minister Najib Razak told reporters. He called for an international team to have full access to the crash site. "If it transpires that the plane was indeed shot down, we insist that the perpetrators must swiftly be brought to justice," he said.
