"Just arrived in Moscow: another long day of back to back meetings," Defence Minister Hishammuddin Hussein said on Twitter, a day after Dutch investigators released a preliminary report on the July disaster.

He will meet with his Russian counterpart Sergei Shoigu and foreign ministry officials, a spokeswoman for Malaysia's Moscow embassy said.

"The visit is related to the events," the spokeswoman said on the condition of anonymity. "The visit will last less than a day."

Hussein was in the Ukrainian capital Kiev on Tuesday and will then visit Amsterdam, the spokeswoman added.

Commenting on the initial findings in the probe the Dutch officials said that MH17 "broke in the air probably as the result of structural damage caused by a large number of high-energy objects that penetrated the aircraft from outside".
