An international group of 2,000 women set off from Istanbul on Tuesday for Turkey's border with Syria, part of a "conscience convoy" to raise awareness of the plight of Syrian women after seven years of civil war.
The convoy of buses is expected to reach the southern Turkish province of Hatay on Thursday, International Women's Day.
The multisided conflict in Syria has killed hundreds of thousands of people and displaced millions from their homes, and the group of activists, from 55 countries, aims to highlight the plight of women in prison in particular.
