Hard to stop a group with an endless number of self-detonating Muslims.

(ALEPPO, Syria) – Six “suicide car” bombings took place in the heart of Kobani Monday as the battle for the hotly contested Syrian town continued on the Turkish-Syrian border, an opposition source said.

Till the filing of this report, the exact number of casualties in the bomb attacks remained unclear.

However, the bombings were blamed on the Islamic State of Iraq and the Levant, or the ISIL, whose 26 militants were also said to have been killed in separate clashes, a source from the Syrian opposition group, Raqqa Revolutionaries Brigade, told Anadolu Agency.

The opposition source also claimed that buildings were destroyed in new violence in the area. It also said that clashes between the Kurdish groups and ISIL militants were still ongoing.

More than 180,000 Kurdish refugees have fled into Turkey since the Islamic State of Iraq and the Levant militant group launched an offensive on Kobani in mid-September. The group is now said to be on the brink of capturing the key town.
