Afghans have called for Prince Harry to face prosecution for the deaths of the people he admitted killing during his time fighting in the country for the UK military. The Duke of Sussex carried out two tours in Afghanistan during his time in the military, including one tour between 2012 and 2013, during which he served as an Apache attack helicopter co-pilot gunner.

The relative of a victim of a 2011 airstrike said to have been carried out by British forces, Mullah Abdullah, was among those saying Harry should be put on trial.

He said he lost nine relatives when his house was hit by an airstrike while he was at the market in the village of Yakhchal in Nahr-E-Saraj district.

He told the AP news agency from the graveside of his dead father, who was among those killed: "We ask the international community to put this person (Prince Harry) on trial, and we should get compensation for our losses.

"We lost our house, our life, and family members, we lost our livelihood and also our loved ones."

Meanwhile, a group of Taliban officials in Helmand province, where British forces were based between 2006 and 2014, echoed the calls as a group of protesters gathered in the provincial capital, Lashkar Gah.

Hameedullah Hameedi, a member of the provincial council in Helmand, told Sky News: "If Harry considered himself a member of a civilised world, this is a shame for him to say that (he killed 25 people).

"And it is an even bigger shame for him to talk about it proudly, like an illiterate person in a poor society with no knowledge and no education.

'Impact on British-Afghan relations'

"We are not only demanding that he be prosecuted in the international court, but also demanding the international community punish him as soon as possible."

"It will undoubtedly have an impact on British-Afghan relations because people are aware that it is a British officer from the Royal Family -- Prince Harry -- who martyred 25 Afghans and committed such crimes," he continued.

Samiullah Sayed, deputy director of education in Helmand, added: "As the prince has admitted, he has martyred 25 people. Not only Harry but all the others who invaded Afghanistan have committed the same crimes. 

"As an independent nation, we will never ever forget the brutality, savagery and cruelty that they performed against our nation and our people."

Harry writes in the book that the killings of the 25 Afghans "was not something that filled me with satisfaction, but I was not ashamed either".

Various members of the British military have taken exception to the duke going public with the number of people he killed.

Retired Royal Navy officer rear admiral Chris Parry told Sky News that he had never heard a colleague "say what their score is" in 35 years of service, including combat.

'Signs of post-traumatic stress disorder'

"I'm afraid to say it's clumsy, tasteless and does not afford respect to the people who have been killed," he said.

Colonel Richard Kemp, a former senior army officer, said Harry's remarks were "ill-judged" and could incite an attack on British soldiers.

But retired former senior intelligence officer Philip Ingram said he recognised in Harry the signs of post traumatic stress disorder (PTSD), and said he needed to be protected, rather than criticised further.
