Six workers were injured when part of a building site on the new high-speed rail line collapsed in the north-western province of Sakarya, Turkey.
The accident occurred when a section of a scaffolding platform gave way during the ongoing construction works on the new rail line, which is to be part of the 533km track linking Istanbul and Ankara.
Turkish State Railways said that an investigation is currently underway to determine the cause of the accident and that there were no other people trapped underneath the debris.
Earlier this week, Turkey Transport Minister Lutfi Elvan said that the official launch of the Ankara-Istanbul high-speed link is being pushed to the end of June due to sabotage attempts, including the theft of cables and other equipment.
Turkish State Railways currently operates three high-speed rail lines between Ankara, Konya and Eskisehir, which are all located in the central Anatolian provinces.
The latest incident comes three weeks after the country witnessed the worst mining disaster that left 301 miners dead, leading to massive protests over poor workplace safety conditions.
