President of the Swiss Confederation Didier Burkhalter called on Friday for an impartial investigation into the crash of a Malaysia Airlines plane on Thursday in eastern Ukraine that killed 298 people onboard.

Burkhalter, who is also the head of the Swiss Federal Department of Foreign Affairs, conveyed his condolences in a statement to the countries whose citizens were among the victims.

The statement further read that Burkhalter also spoke on telephone with Frans Timmermans, Foreign Affairs Minister of the Netherlands which suffered the most casualties, and expressed his condolences to the victims and their families.

There were no indications so far that any Swiss citizens lost their lives in the plane crash, said the senior official.

Burkhalter offered to send Swiss experts to Ukraine to help investigate the cause of the crash, identify the bodies of the victims and provide support in the laboratory work.

Moreover, Burkhalter, who meanwhile holds the rotating presidency of the Organization for Security and Co-operation in Europe (OSCE), welcomed the agreement of militia in eastern Ukraine to secure the site of the crash for rescue teams and investigators.

Burkhalter said that the security body was making efforts to create a humanitarian corridor allowing access to this region to recover and identify victims and to start an impartial and thorough probe into the tragedy as soon as possible.

It was reported that two video conferences between the OSCE, Ukrainian and Russian representatives were held overnight and a third one was scheduled to take place on Friday.

According to RIA Novosti, 30 staff with the OSCE have arrived at the crash site.

The OSCE confirmed earlier on Friday that around 30 monitors have arrived at the crash cite to observe the crash case, but due to the poor infrastructure in the region, they found hard to report the situation to their headquarters.

Malaysia Airlines Flight MH17, a Boeing 777, was en route from Amsterdam to Kuala Lumpur when it went down Thursday in eastern Ukraine with 298 passengers and crew aboard. There were no survivors.
