Russian forces are raping and hanging women who are unable to escape their savage invasion, Ukrainian MPs have claimed.
Lesia Vasylenko, an MP for Ukraine 's opposition Holos party, said some women over 60 had committed suicide after being accused by Putin's forces to stop the horrific attacks.
Other vulnerable women were unable to escape the invading troops in Kyiv and its suburbs of Bucha and Irpin and have been subjected to the barbaric sex assaults, she said.
The MP, who visited the House of Commons with fellow MPs Olena Khomenko, Maria Mezentseva and Alona Shkrum, told journalists Putin had 'changed his strategy to target the most vulnerable groups of women and children'.
She said, according to The Mirror: 'Most of them were executed after being raped or took their own lives.

They also want the crimes to be formally documented as war crime evidence against Putin.
The MPs said a generation of children in Ukraine are being traumatised, with one child as young as five already on anti-depressants.
