The Ukrainian city of Kharkiv is facing a heavy bombardment at the moment as Vladimir Putin revs up his airstrikes on Ukraine.
Many of its key landmarks, including Freedom Square and the Opera House, have been hit as Ukrainian troops defend the city.
It is becoming one of the most famous cities in the world due to its role in the war with Russia, and President Volodymyr Zelensky has described Russia's attack on the city as 'war crimes'.
The attacks have led to huge numbers of people fleeing the country already, an estimated one million, while at least 10 people were killed and 35 injured in attacks on the city earlier this week. More people have now been killed in the city.
When the square was attacked, Zelensky said: "This is terror against Ukraine. There were no military targets in the square - nor are they in those residential districts of Kharkiv which come under rocket artillery fire."
So where is Kharkiv and why has it seen so much of the war?

Where is Kharkiv?
Kharkiv is in northeastern Ukraine, around 250 miles east of Kyiv.
The city is still reported to be under Ukrainian control despite sustained Russian attacks in the form of airstrikes.
Russian troops have not had as much success as it was feared when war broke out.
Historically, Kharkiv is culturally important as well, described by Britannica as "one of the most important cultural and educational centres of Ukraine". A hub of writers and developments in the arts developed there during the 19th and 20th centuries despite Soviet rule.
This is not the first time the city has seen war and it changed a number of ties during World War Two when it was occupied by German invaders.
An enormous portion of the city was destroyed and had to be rebuilt after the war.
Why is there so much fighting in Kharkiv?
Along with Mariupol, Chernihiv and the capital of Kyiv, the main cities of Ukraine are strategically important and are likely to see more of the fighting - Kharkiv is only 20 miles from the Russian border
The city appears to be important strategically too as it is well connected, with highways to both Moscow and Kyiv, as well as Crimea.
As the second-largest city in Ukraine and with a population of around 1.4 million people before war broke out, it has a major airport.
Taking Kharkiv could be key to the Russian advance on Kyiv, which is now reported to be stalling, due to what the UK Ministry of Defence today described as "staunch Ukrainian resistance, mechanical breakdown and congestion".
On Wednesday, 21 people in the city were reported to have been killed with 100 more injured.
