Turkish men have donned miniskirts to denounce violence against women at a protest in Istanbul after a 20-year-old student was beaten to death after trying to fight off a man attempting to rape her.

Ozgecan Aslan was abducted on 11 February. She had used pepper spray to fend off the attacker, before being beaten and stabbed. Her body was discovered days later in a riverbed.

The particularly brutal assault has sparked widespread outrage. The hashtag #ozgecanicinminietekgiy has become a top trend on social media, with men in Turkey and Azerbaijan wearing a miniskirt to denounce the attack.

Rights groups have noted a rise in violence against women in the last year, prompting calls for more protection from the state.
