Militants of the Takfiri group, ISIL, killed 120 civilians in a 24-hour rampage through the Kurdish town of Kobani in what a monitor said Friday was one of the extremists' "worst massacres" in Syria.

The killing spree in the town, which has become a symbol of Kurdish resistance, was widely seen as vengeance for a series of defeats inflicted on the terrorists by Kurdish militia in recent weeks.

It began after three ISIL suicide bombers blew up vehicles at the entrances to the town on Thursday clearing the way for fellow Takfiris to enter.

Women and children were among the slain civilians whose bodies were found in their homes and in the streets, the Syrian Observatory for Human Rights said.

"According to medical sources and Kobani residents, 120 civilians were executed by ISIL in their homes or killed by the group's rockets or snipers," Observatory director Rami Abdel Rahman told AFP.

"When they entered the town, the militants took up positions in buildings at the southeast and southwest entrances, firing at everything that moved."

Local journalist Mostafa Ali said that there was no military dimension to the ISIL assault on Kobane.

"ISIL doesn't want to take over the town. They just came to kill the highest number of civilians in the ugliest ways possible," he told AFP.

The Takfiri group also executed 26 civilians in a village outside Kobani on Thursday, the Observatory said.

"Every family in Kobani lost a family member on Thursday," Kurdish activist Arin Shekhmos said.
