AMSTERDAM (Reuters) - Dutch prosecutors said on Monday they are looking for witnesses in eastern Ukraine who may have seen a Russian-made BUK rocket being fired at Malaysia Airlines flight MH17, saying this was the "leading scenario" in their crash investigation.

The Netherlands is heading an international probe into the July 17 disaster, which killed 298 passengers and crew, two-thirds of them Dutch nationals.
