Belarus on Wednesday buried more than 1,200 Jewish Holocaust victims whose remains were unearthed this year after builders stumbled across a Nazi-era mass grave beneath a construction site in a residential area.

Soldiers were called in to the city center of Brest on Belarus' western border with Poland where they exhumed the bones of 1,214 people killed during the Nazi occupation at the site of what served as a Jewish ghetto from 1941-42.

Their remains were buried on Wednesday in 120 blue caskets embossed with the star of David that were laid side-by-side and two-deep in a giant grave in a city cemetery to the north of Brest at a ceremony led by a local Jewish rabbi.
