Malaysia's transport minister says the country is ``deeply concerned'' that the site in Ukraine where a Malaysia Airlines jetliner was shot down with 298 people onboard ``has not been properly secured.''
Liow Tiong Lai said at a news conference Saturday in Kuala Lumpur that ``the integrity of the site has been compromised, and there areindications that vital evidence has not been preserved in place.''
He called for immediate access for Malaysia's team at the site to retrieve human remains.
He said ``we need the support of the world to ensure that the site is not tampered with and that we have access to the site.''
A team of 30 international observers has arrived in eastern Ukraine however, the observers, mostly from the Organization of Security and Co-operation in Europe,say their access to the
wreckage is being severely limited by the pro-Russian rebels who control the region.
Western leaders are demanding the rebels give independent investigators swift and unlimited access to the crash site.
Liow, who again defended Malaysia Airlines' flying in Ukrainian airspace, said a Malaysian team arrived in Kyiv earlier Saturday, two days after the plane went down.
