Horrific accounts of rape and abuse at the hands of trusted charity workers have been given to British MPs as they investigate exploitation in the charity sector.

Shocking stories include a girl being given one dollar - before being raped by an aid worker.

Young boys and girls revealed a decade ago that they were being abused and their families told how they were powerless to act, the International Development Committee heard.

Aid workers are accused of raping and abusing women in the Caribbean nation.Pictured Port-au-Prince, Haiti, 2010

Corinna Csaky set out evidence from an investigation she carried out in 2008 into the abuse of children by humanitarian staff and peacekeepers.

Shockingly, Mrs Csaky said an advance copy was sent to the CEO of Oxfam and all major international (non-governmental organisations) NGOs, in 2008, years before the earthquake abuse.

However, it is now claimed authorities did not do enough to act after 23 organisations were implicated.

A report by Corinna Csaky was delivered to organisations in 2008 but claims of rape and abuse continued for years

In the report it was claimed the majority of abuse allegations were made against troops associated with the UN Department of Peacekeeping Operations (DPKO) 'particularly in Haiti and Côte d'Ivoire'.

A 14-year-old boy in Cote D'Ivoire quoted in the report said workers at a peacekeeping camp would sometimes ask for girls his age.

'Often it will be between eight and 10 men who will share two or three girls. They also use their mobile phones to film the girls.'

Children and parents said they were unable to report the abuse.

'The people who are raping us and the people in the office are the same people,' according to a young girl in Haiti.

Oxfam's Penny Lawrence resigned as Deputy Chief Executive of the charity after the scandal

Allegations of attacks by charity sector employees have been exposed since a scandal involving Oxfam in Haiti emerged.

The charity's staff were deployed to the nation in 2010 after a devastating earthquake with as many as 53 aftershocks rocked the Caribbean country.

Estimates suggest between 100,000 and 160,000 died.

In the wake of the disaster aid workers stayed in villas as they helped piece the nation back together. But years later it emerged many had used prostitutes during their work there.

There were accusations many girls were underage - although the charity insists this was never proven.

Among the claims made at the time, it was said prostitutes were even handed Oxfam t-shirts to wear, while others were asked to trade sex for goods.

Penny Lawrence, resigned as Deputy Chief Executive of the charity saying she took 'full responsibility' for the behaviour of staff in Chad and Haiti 'that we failed to adequately act upon'.

Many people in Haiti lived in slums after the earthquake and some turned to prostitution. The MPs on the International Development Committee were told these women were used by charity workers while some were raped

Since then, some 1,100 complaints over safeguarding in aid agencies have been made, according to the Charity Commission.

They included a young boy in Haiti who said a homeless girl was taken to a man who worked for an aid organisation.

'He gave her one American dollar and the little girl was happy to see the money,' the boy said.

'It was two in the morning. The man took her and raped her. In the morning the little girl could not walk.'

A father in Cote d'Ivoire said: 'They don't even hide what they are doing.'

The testimonies were part of a report, No One To Turn To, by Ms Csaky for Save the Children.
