Angelina Jolie and William Hague Open London Summit on Rape in War ZonesIBTimes UK

Foreign Secretary William Hague and UN special envoy Angelina Jolie are set to open a four-day international conference on sexual violence against women in conflict zones.

The Global Summit to End Sexual Violence in Conflict in London will address key issues pertaining to sexual assaults. Scores of senior government officials, experts, law enforcement officials, NGOs and survivors from more than 100 countries are scheduled to take part.

The summit, hosted by Hague and the Hollywood actress Jolie, who is also special representative for the UN High Commission for Refugees, will take place at the Excel Centre in east London. This is said to be the largest gathering of its kind.

Ahead of the inauguration, US Secretary of State John Kerry, who will also participate, wrote in the Evening Standard newspaper: "Sexual violence plagues every country. Acts of sexual violence demean our collective humanity."

"We will pool our expertise, diplomatic skills and resources toward the common goal of relegating sexual violence to the annals of history where it belongs."

Hague also hopes the summit, the culmination of a two-year-long campaign, will be a "turning point" in tacking the issue.

Others have expressed concerns over the UK government's alleged hypocrisy on the subject citing the failure of government authorities while dealing with war refugees and victims of sexual violence.

The Refugee Council's woman advocacy manager Anna Musgrave told the Guardian: "This summit demonstrates there is a dangerous lack of joined-up thinking when it comes to tackling sexual violence against women. These are the same women,"

"On one hand, you've got real progress being made in conflict zones overseas, but when those same victims make it to UK shores it's a completely different story. Women often aren't believed, and instead of being protected they're further traumatised by the asylum system. It's critical that the government tackles this issue with the same gusto at home as it's doing abroad and protects the survivors of sexual violence."

UN Secretary General Ban Ki-Moon is also expected to address the forum through a video message on the final day.
