Of the 150 Palestinian prisoners released, 98 were detained without charge, the report stated.
119 of those freed were children, while the remaining 31 were women.
Israel often uses administrative detention against Palestinians, a procedure which allows Israeli authorities to hold prisoners indefinitely without charging them or allowing them to stand trial.
According to Israeli human rights group B’Tselem, there are around 1,300 Palestinians in administrative detention, including children aged between 16 and 18.
