Passed away is used as a gentler way of saying someone died. It’s very commonly used.

Sad morning. Lebanese football player Mohammad Atwi has passed away after fighting for his life for a month. He was hit with a stray bullet and was in a critical state. Such a young talent gone too soon. RIP. #Lebanon #محمد_عطوي

After a tough few months I want to thank everyone who sent condolences after my beautiful Mum Betty passed away. I will forever be indebted to the staff in ICU at St Jamses hospital for the care, compassions & dignity they showed to my mum in the last few months of her life 💔
