An independent inquiry probing allegations of unlawful killings by British armed forces in Afghanistan was officially launched today.
Chairman Lord Justice Haddon-Cave described claims made against military personnel as "extremley serious" as he vowed to "get to the bottom" of claims.
The serving judge also issued a call for evidence for anyone with evidence of illegal activity in the war-torn country between 2010 and 2013.
In his opening statement on Wednesday the chairman said the allegations include "numerous unlawful killings" by British armed forces between 2010 and 2013.
The serving judge said allegations included "that these unlawful killings were covered up to prevent what had taken place ever coming to light".
He added: "It is clearly important that anyone who has broken the law is referred to the relevant authorities for investigation.
"Equally, those who have done nothing wrong should rightly have the cloud of suspicion lifted from them.
"This is critical, both for the reputation of the armed forces and the country."
The inquiry was launched in the wake of legal challenges to the Government by Leigh Day solicitors on behalf of the Saifullah and Noorzai families.
Last year the families of eight people alleged to have been killed in two separate incidents during night raids in Afghanistan welcomed the announcement to launch the inquiry.
Tessa Gregory, a partner at the law firm Leigh Day, said: “Our clients welcome the official launch of the Independent Inquiry relating to Afghanistan and look forward to working with Lord Justice Haddon-Cave and his inquiry team as they seek to establish the truth which has been hidden for too long.
“Throughout years of secrecy and cover-ups our clients have fought tirelessly for justice for their loved ones’ deaths and they hope that a bright light will now be shone on the practices and command of UK special forces in Afghanistan.
“We would urge anyone with information to come forward to the inquiry so that the full picture can finally be examined.”
Established under the 2005 Inquiries Act, the probe will have the power to compel witnesses to give evidence and order documents to be produced.
But the chairman made clear some evidence would need to be provided in closed hearings "and all necessary steps taken to protect sensitive material" and witness security.
The inquiry is expected to release an interim report within 18 months, he added.
