The siege was mainly centered in the Hasakah Security Box, and the neighborhoods of Halko and al-Tayy in Qamishli,[7] preventing the entry of forces loyal to the Syrian government as well as supplies and fuel to the areas.[8] The sieges began on 10 January 2021 after the two sides failed to reach an agreement regarding a wide range of issues, including release of AANES prisoners.[9][8]
