The warning from the UN Organization Stabilization Mission in DRC (MONUSCO) comes after two of the mission’s utility helicopters faced hostile fire on 26 December from “two localities under M23 control,” according to a MONUSCO press release.MONUSCO said the helicopters were unarmed and are “routinely used for medical evacuation for both UN personnel and civilians.”They were fired upon while undertaking a “routine flying certification” 20 kilometres north of Goma, the provincial capital of North Kivu province in eastern DRC that the M23 occupied last month for 11 days.MONUSCO added that this was the second time that UN helicopters had been “deliberately targeted by M23 elements” during December.The M23 is made up of former DRC army troops who mutinied in April, and named after a 23 March 2009 peace agreement that they reportedly say has not been implemented. For its part, MONUSCO is deployed in DRC to protect civilians, humanitarian personnel and human rights defenders, among other tasks set by the UN Security Council.“MONUSCO reminds that peacekeepers are in the exclusive service of peace, and that any attack against them constitutes a war crime,” the mission said. “Those responsible for such acts will be prosecuted and brought to justice.”The M23 has this month participated in peace talks with the DRC Government in the Ugandan capital of Kampala. Its troops withdrew from Goma at the end of November under the supervision of some of the 1,500 MONUSCO peacekeepers deployed in the city of one million. This was in accordance with requirements laid out in a communiqué issued by the regional intergovernmental group known as the International Conference on the Great Lakes Region (ICGLR).MONUSCO said it has reported the recent attacks to ICGLR’s Joint Verification Mechanism in Goma, which monitors the border between DRC and Rwanda.It added that the 26 December attacks took place at approximately 8 p.m., with initial fire originating from Kibumba, a town about 25 kilometres north of Goma, and a second round of fire coming from Kanyamahoro, another locality in the region.
Terrified victims have described how the “well-spoken” raider seems to know the layout of their homes, down to where safes are hidden.He also shows a knowledge of their daily routines, often striking late at night, entering unlocked doors or windows, sometimes waiting until owners let their dogs out.During the raid on the Goodwood estate in January 2016, the Duke, 61, was struck on the head with a blunt object, before being forced to open a safe.

Items stolen in raids believed to have been carried out by the Night WatcherCredit:Surrey Police/PA The raider, who wears a balaclava and dark clothing, usually escapes on foot without leaving any forensic clues.He has struck seven times over the past three years in Surrey, Berkshire, Sussex and Kent, making off with more than £7 million in valuables. Similar raids have taken place around every six months, with detectives working on the theory that he strikes after spending the proceeds from each burglary.Det Insp Dee Fielding, from Surrey Police, said: “We do not believe this to be an opportunist burglar, but someone who has specialist knowledge and skills – possibly ex-forces or from a similar background.“The burglaries all appear to be the work of someone who knows exactly what they are doing and who is incredibly decisive in their actions. On each occasion, unnecessary levels of violence have been used.” Some of the family heirlooms stolen during the burglariesCredit:Sussex Police/Solent News & Photo Agency Police are hunting a violent armed burglar who uses “special forces” techniques and military-style expertise to stake out and strike at multi-million pound properties across the Home Counties.Among those targeted were the Duke and Duchess of Richmond, who were forced to hand over £700,000 of heirlooms after being tied up during a raid at Goodwood estate in Sussex.Police believe the burglar, dubbed The Night Watcher, spends months staking out secluded houses, sometimes hiding in the grounds, in order to build up an intimate understanding of the daily movements of his victims.As well as being an expert in covert surveillance, the raider has also shown athletic prowess, scaling high walls and fences while evading detection by sophisticated security systems.Police said he also displays a chilling degree of nonchalance, even when entering a property with multiple occupants. Once inside, he uses a sawn-off shotgun, cable ties and extreme violence in order to force the home owners into giving up their valuables.Video: Terror of one of The Night Watcher’s victims Among the items stolen were a £400,000 diamond tiara and an emerald ring given by Charles II to Louise de Kerouaille, his mistress.Police believe the first raid took place in November 2014, when two women were attacked in their home near Kingswood Golf Club in Surrey and needed treatment in hospital.
