His mom — a doctor and 'a true angel' — died when mortar struck her home in Sudan

Nagwa Khalid Hamad, who died when mortar hit her home in Khartoum, at a wedding in in 2019. Her son says: "I don't even recall whose wedding it was but all i can remember is my brother, sister, mom and myself were there and we were happy." He describes her as "a very calm person." If he was upset, he says, "she would say to just take it in, just breathe it in and don't worry about it." (Khalid Osman)

Nagwa Khalid Hamad, age 66, died last Sunday when a mortar collided with her home in Sudan's capital, Khartoum. Hamad was an ophthalmologist beloved by her patients. She was also a wife and mother of four. She is one of at least 400 people killed since conflict erupted last Saturday.

Intense fighting between the army and the Rapid Support Forces paramilitary group has ripped through Khartoum and other parts of Sudan. Normally bustling areas have been overtaken by air strikes, artillery, gunfire and tragedy.
