Outside a flooded Ukrainian city, specialists warily sweep the ground for hidden bombs

The scene in a low-lying field northwest of the battered and flood-soaked Ukrainian city of Kherson on Friday could almost be described as a ballet of bomb detection.

A team from the British-based HALO Trust, a humanitarian non-governmental organization, swept its mine detectors in precise, deliberate synchronization, left and right.

Every once in a while, a detector would scream, prompting the operator to pause and check the ground. There were some false alarms when CBC News visited the area on Friday.

The six person unit was going over what was, for them, familiar ground near the village of Yevhenika — a bucolic little hamlet of bored cows and gently rolling poppy, heather and sunflower fields along a river system connected to the now-destroyed Nova Kakhovka dam.

Water from the vast Kakhovka reservoir poured through the breach in the dam, swamping agricultural land and dozens of villages and towns downstream.

The floodwaters swamped many areas that had been the front lines before last fall, when Ukrainian forces drove most of the Russian troops out of nearby Kherson and back across the Dnipro River.

The flooding throughout southern Ukraine has dislodged and shifted around a variety of anti-personnel and anti-vehicle mines — sometimes spreading them over fields that had already been cleared and put back into agricultural use.

"These were Russian-laid mines all over here," said Jasmine Dann, a Canadian who is the regional operations manager for the HALO Trust in Ukraine, citing a giant Google Earth map of the region.

"The Russians occupied the southern side of the river here, Ukrainians were situated further to the north. So all of the minefields that he was working on right now are all Russian-laid minefields."

One nearby field had been deemed cleared before the flood and was planted with sunflowers. It remained totally underwater on Friday and will have to be swept again, Dann said.

"So as soon as that water is gone, we will be back there trying to clear those mines."

The sense of frustration came through loud and clear.

"It's the same as all of our de-mining work — it takes patience," Dann said. "It takes time and just a desire to make sure that when we give back that land, it's fully safe for communities."

Last winter, the Canadian government pledged $21 million for mine-clearing projects in Ukraine, including the HALO Trust. It plans to have 1,200 mine clearing technicians in the field by end of the year.
