Pilot error or technical fault 'caused Russia plane crash'

Pilot error or a technical fault is thought to be the cause of Sunday's Black Sea plane crash that killed 92 people, Russia's transport minister has said as the nation held a day of mourning for the victims.

All 84 passengers and eight crew members on the Russian military's Tu-154 plane are believed to have died on Sunday when it crashed two minutes after taking off from the southern Russian city of Sochi. Passengers included dozens of singers in Russia's famous military choir, nine Russian journalists and a Russian doctor known for her charity work in war zones.
