AMSTERDAM: Dutch prosecutors are still awaiting US intelligence reports on the crash of Malaysia Airlines Flight MH17 but American laws on passing on such information to criminal investigations are complicating the process, the Dutch government said on Tuesday.

The Dutch have the lead role in investigating the downing of the Boeing 777 aircraft, which crashed over rebel-held territory in eastern Ukraine in July with the loss of all 298 people aboard, two thirds of them Dutch.

With the crash site too dangerous to access due to fighting, they have been relying mostly on publicly available information to carry out a remote investigation.

The US and Russian governments have both said who they believe was behind the aircraft’s downing, each citing intelligence information that is not publicly available.

The United States said its satellite imagery proved it was shot down with a ground-to-air missile by Russian-backed rebels. Russian says a Ukrainian military aircraft downed it.

“It is desirable for prosecutors to receive further information from the US in connection with the criminal investigation,” the government said in a letter to Parliament.
