Hello. Some Ukrainians are fighting for Russia in the war - we find out why. The trial of a mother accused of murdering her children has shone a light on postpartum psychosis in the US. And view what a Red Arrows stunt pilot sees during an aerial display. 

Clancy admits she carried out the killings but has pleaded not guilty to murder charges. Her defence argues she was suffering from hallucinations and delusions that began after the birth of her third child. Prosecutors allege she made a calculated decision to intentionally kill Cora, five, Dawson, three and Callan, who was eight months. 

The rare condition is considered a medical emergency, and can see patients experience mania, depression or a mixture of both. They also endure psychotic symptoms, such as hearing voices, and in uncommon, severe cases, they may harm or kill themselves or other people. 

The major barrier standing in the way of awareness and better treatment of the illness in the US is that it's not included in the mental health handbook published by the American Psychiatric Association, experts say. Without a mention there, the illness does not get discussed in medical school textbooks, students do not learn about it, and people don't talk about it much, says Veerle Bergink, a professor of psychiatry and the director of the Mount Sinai Women's Mental Health Center. However, the illness is treatable and patients do recover.

• Watch: Why postpartum psychosis is central to the trial. 

• Court: Clancy was "begging for help" before the killings, her ex-mother-in-law testified, echoing others who've spoken about her mental health.

• Ex-husband: In the early days of the trial, Clancy's former partner gave evidence about finding his children when he came home from buying dinner.
