ISIL terrorists subjected a group of teenagers from the Syrian battleground town of Kobani to a string of abuses, including torture, during six months in captivity, Human Rights Watch said on Tuesday.

A group of 153 schoolchildren was taken hostage by ISIL in May en route to their hometown of Kobani after sitting exams in the Syrian city of Aleppo, according to HRW.

ISIL released the last 25 hostages in late October.

Interviewed in Turkey where they were given refuge, four boys from the group recounted regular beatings with cables and a hose and being forced to watch videos of ISIL militants in combat and beheading captives.

ISIL terrorists forced the children -- aged 14 to 16 -- to pray five times a day and beat those who tried to escape or did poorly in compulsory religious lessons, the New York-based group said.

"Those who didn't conform to the program were beaten. They beat us with a green hose or a thick cable with wire running through it. They also beat the soles of our feet..." one boy was quoted as saying.

"They made us learn verses of the Koran and beat those who didn't manage to learn them. When some boys tried to escape, the treatment got worse and we were all punished and given less food."
