Alright kiddo, so Zafar is a city in Yemen. Yemen is a country located in the Middle East, that's far away from where we live. Yemen has had a lot of problems lately like wars, which is when people fight each other with weapons.
Zafar is a really old city with lots of history and ruins from a long time ago. It used to be an important center of trade and learning, which means people went there to buy and sell things and also to study and learn new things.
Nowadays, there are still people living in Zafar, but the city's infrastructure and buildings have been damaged by the war and it's not a very safe place to be. The people who live there have to deal with a lot of challenges and struggles just to be able to live their daily lives.
So, in short, Zafar is a historical city in Yemen, but unfortunately, it has been affected by the ongoing war in Yemen and is currently not a very safe place to be.
