Malaysia is "deeply concerned" about whether or not the crash site of flight MH17 is being properly secured, the country's transport minister said Saturday.
"We feel for their families. And we promise to do all we can to ensure that the investigation is completed, and that justice is done," Minister of Transport Liow Tiong Lai said.
He said a team had arrived in Kiev and that he and other officials would travel there as the investigation into the tragedy that left 298 people dead and a vast crime scene continues.
He also said the full list of passengers aboard the downed plane was to be released later in the day. Liow again defended the plane flying in Ukrainian airspace and stressed the need to be able to retrieve victims' remains.
"We must not forget that it is a human tragedy," he said. "Days after the plane went down, the remains of 298 people lie uncovered." A report from CNN said that some bodies remained strapped in seat belts, wearing inflight headphones.
Malaysia "calls for those responsible to be found, and to face the full force of justice without delay," Liow said.
Ukraine has accused Russia of helping rebels destroy evidence at the crash site.

Officials in Kiev said 38 bodies had been taken to the rebel-held city of Donetsk by separatists. The Ukraine government said in a statement that they intended "to carry away plane fragments to Russia," the Associated Press reported.
Ukraine also echoed demands made by President Obama on Friday that investigators be granted access to the wreckage.
The plane flying from Amsterdam to Kuala Lumpur was shot down Thursday in an area close to the Russian border where for months government troops and pro-Russia separatists have been fighting.
The U.S. says a surface-to-air missile took down the jet. The Boeing 777 was flying over Ukraine's war-torn Donetsk region, the site of fighting between Ukraine and pro-Russian Ukrainian separatists.
An international delegation visited the crash site Friday evening but was only allowed a superficial visit to see one small portion.
The jetliner was carrying 298 people, including 80 children. The victims came from 11 countries. They included an acclaimed AIDS researcher from Amsterdam, a nun and teacher from Sydney, a Dutch senator, a Malaysian actress and a World Health Organization spokesman.
One American with dual Dutch citizenship was among the dead.
