At least six doctors have reportedly been injured and four other people killed after the shelling of a hospital in eastern Ukraine, following Russia’s invasion of the country.

Russian President Vladimir Putin declared war in a pre-dawn televised address, saying he was trying to “denazify” the country.

Within hours, explosions and gunfire were heard as helicopters and armoured divisions with tanks and missile launchers crossed Ukraine’s northern and eastern borders.

The WHO has already issued a declaration that all parties need to ensure that health facilities, workers, patients, transport and supplies are not targeted.
