Russia-Ukraine war: All about Day 12, Oil hits 13-year high

MARCH 7: Oil prices have soared to the highest level since 2008 after the US said it was discussing a potential embargo on Russian supplies with its allies.

Brent crude - the global oil benchmark - spiked above $139 a barrel in Asia trade, before easing to below $130.

Energy markets have been rocked in recent days by oversupply fears triggered by the Russian invasion of Ukraine.

Consumers are already feeling the impact of higher energy costs as fuel prices and household bills jump.

Things to know as the Russian invasion of Ukraine enters its 12th day:

UK defense officials have said they believe Russian forces made minimal gains over the past 48 hours, with its troops bogged down by stiff Ukrainian resistance and poor logistical support.

But Ukrainian commanders have warned that Russian forces have been regrouping and are preparing to launch an all-out assault on the capital Kyiv.

Moscow's forces have been heavily shelling towns on the periphery of the city and re-supplying tank units with fuel moved in from Belarus in preparation for the attack, officials said.

In the south-eastern city of Mariupol, Russian shelling has killed dozens of people and Ukrainian President Volodymyr Zelensky has warned Moscow's troops that his forces will pursue any soldier that commits war crimes to the grave.

Senator Marco Rubio, the highest-ranking Republican on the Senate Intelligence Committee, told CNN on Sunday that imposing a no-fly zone over Ukraine would almost certainly mean "starting World War Three”.

Sanctions continue to target Moscow's economy, with Netflix, American Express, KPMG and PricewaterhouseCoopers among the latest major companies to suspend services in Russia.

Four people including a mother and two children die in mortar fire as residents flee the town of Irpin near Kyiv.

Ukrainian defence officials have warned Russia is preparing to launch an all-out assault on Kyiv.

Russia's military action will not stop until Moscow's demands are met, Vladimir Putin says.

The global nuclear watchdog says it is very concerned by reports that a nuclear plant is under the orders of a Russian commander whose forces seized it.

A fresh bid to evacuate civilians from the southern city of Mariupol fails - the city council blamed Russian shelling.
