Loud explosions heard in Odessa

One city in the south-west of Ukraine that is bracing for attack is the port of Odessa. The south of Ukraine is where much of Russia's military might is attempting to make territorial headway. Loud explosions were heard in the city overnight.

Russia says it is making a new attempt to provide humanitarian corridors for civilians fleeing fighting in Ukraine, after Kyiv rejected previous plans as unacceptable.

And as people plan to escape from the besieged city of Mariupol, we hear from one survivor, retelling their personal account of what it was like to flee during dangerous attacks.
