Seven killed in drone attack on bus in Russia-controlled part of Ukraine

Seven people have been killed and 11 others injured in a drone attack on a passenger bus travelling through a Russia-controlled part of Ukraine, an official said.

Denis Pushilin, the Kremlin-installed leader of Ukraine's eastern Donetsk region, said the bus was hit in the early hours of Wednesday as it was travelling between Moscow and Simferopol, in Russian-occupied Crimea.

Russia downed more than 350 drones overnight, according to Russian officials.

The drone strike comes a day after a massive Russian assault on cities across Ukraine killed at least 22 people, including several women and children.

At least 50 drones were downed over the Leningrad region northwest of Moscow, according to the regional governor Alexander Drozdenko.

The region includes the city of St Petersburg, which from Wednesday will host the annual International Economic Forum, an event designed to showcase Russia to the world.

Organisers say that delegations from more than 130 countries and territories will attend, including Chinese Vice-President Han Zheng, and the presidents of Uzbekistan and Tanzania.
