Almost 100,000 trapped after Russia's 'powerful bombs' rock Ukraine's Mariupol

New Delhi: Almost 100,000 people are trapped in the Mariupol after two "super-powerful bombs" from Russia rocked the city on Tuesday.

As per reports, the Ukrainian authorities are making a fresh attempt at rescuing civilians from the besieged southern port city.

"Almost 100,000 people are trapped among the ruins of the Ukrainian city of Mariupol, facing starvation, thirst and relentless Russian bombardment," President Volodymyr Zelensky said as the UN sharpened demands for Moscow to end its "absurd" and "unwinnable" war.

Tens of thousands of residents have already fled the besieged southern port city, bringing harrowing testimony of a "freezing hellscape riddled with dead bodies and destroyed buildings", according to Human Rights Watch.

In his latest video address Tuesday, Zelensky said more than 7,000 people had escaped in the last 24 hours alone, but one group travelling along an agreed humanitarian route west of the city were "simply captured by the occupiers."

He warned that many thousands more were unable to leave as the humanitarian situation worsens.

Kyiv is under curfew until Wednesday morning as Russian troops continue their advance on the capital.

After several rounds of inconclusive negotiations, Russia said that it would like its peace talks with Ukraine to be "more substantial." The Kremlin also said Tuesday that it would only use nuclear weapons in the context of the Ukraine conflict if it were facing an "existential threat."

So far, a Kremlin-allied tabloid has reported that 9,861 Russian troops have been killed and 16,153 injured in the nearly month-old war, 20 times the official tally.
