• Syria: Russian sappers begin de-mining ancient ruins of Palmyra

    Russian sappers from the International Mine Action Centre were deployed on a special assignment to assist the Syrian Army with bombs disposal and mine clearance operations among the ancient ruins of Palmyra, Wednesday, following the liberation of the city from so-called Islamic State (IS, formerly ISIS/ISIL) militants. The robotic complex called Uran-6 was also utilised in excavating areas suspected to contain traps and mines. Since the beginning of demining operations in Palmyra, Russian sappers have cleared approximately four kilometres (two miles) of roads and neutralised more than 430 explosive devices.

  • Syria: Army Planting Banned Landmines

    A 28-year-old former Syrian army deminer from Jisr al-Shughour in Syria's northern Idlib Governorate told Human Rights Watch that in January, local residents saw the Syrian army plant landmines at Hasanieih (حسانية), Derwand (دروند) and Jiftlek (جفتلك), along routes used by refugees to reach Turkey. In early February, he visited Hasanieih and found landmines planted "between the fruit trees" 3 meters from the border in two parallel lines, each approximately 500 meters long. Local villagers told him that the army had informed farmers in the area that they need army permission to enter the orchards, but had not told them that the area was mined. At the beginning of March, the deminer, together with his cousin and three volunteers, removed approximately 300 PMN-2 antipersonnel mines from Hasa...

    Russian sappers continued to clear residential areas of eastern Aleppo of explosive devices on Wednesday, after a big land mine was found in an old truck in Bustan al-Qasr.

The Head of the International Mine Action Centre of the Russian Armed Forces, Igor Mikhailik, stated, that, "with the help of special equipment the radio signal was muffled and sappers neutralised this explosive device." He noted that, "the vehicle was prepared as a ‘jihad-mobile,’ placed in a densely populated area and was designed to be blown up during the afternoon, when there is a large number of both cars and local residents." ...
