The trial of four people accused of shooting down Malaysia Airlines flight MH17 in 2014 has begun. The three Russians and a Ukrainian, who are expected to face murder charges, are still at large.
Investigators said the Boeing 777 with 298 people on board was brought down by a Buk missile system on 17 July 2014. The missile is believed to have been fired from a military base in Russia.
Russia has repeatedly denied involvement in the incident.
Passengers of 10 different nationalities were on board the plane at the time of the incident. The majority of the passengers were Dutch.
The ill-fated plane had departed Schiphol airport for Kuala Lumpur when it was downed.
The pre-trial hearings are expected to take at least two weeks. During this time, procedural aspects of the case will be covered.
