"Some attacks happened on the outskirts of the capital. Some attacks happened deep inside the territory of Ukraine. We're getting the first information about casualties among our soldiers and among the civilian population," he added.

Giving the update on the situation in Ukraine, the envoy said "we have first civilian casualties even on outskirts of the capital." "There's fighting in some areas. According to information of our Ministry of Defence, Ukrainian side shot down 5 Russian fighter planes, 2 helicopters, we destroyed 2 tanks and several trucks," Ukrainian envoy added.

The Indian embassy in Kiev earlier today said the present situation in Ukraine is highly uncertain and Indian citizens should remain calm and safe amid escalating situation in Ukraine following the Russian military operations.

The advisory was issued in the light of Russian military operations in the Donbas region which has prompted criticism and sanctions from several western countries.

Russian President Vladimir Putin said special military operations are being launched "to protect" the people in the Donbas region. He also warned other countries that any attempt to interfere with the Russian action would lead to "consequences".

Leaders from a number of countries including the UK, the US, Canada, and the European Union have condemned Russia's military operations in the Donbas region.

Amid Russia's military operations, Ukraine has introduced martial law and urged citizens to remain calm. Ukraine has closed the airspace for civilian aircraft "due to the high risk of aviation safety."

Defending Russia's decision to take military action in the Donbas region, the Russian envoy to the UN Vasily Alekseevich Nebenzya said that the Russian operation is aimed to protect residents in eastern Ukraine.
