Kobane, June 26 (RHC)-- Islamic State militants have reportedly killed more than 120 civilians since launching a fresh attack on the Syrian border town of Kobane. Eyewitnesses say that the terrorists "fired at everything that moved" after entering on Thursday, according to the Syrian Observatory for Human Rights.

Meanwhile, the United Nations reports that a separate Islamic State attack on the north-eastern city of Hassakeh has displaced nearly 60,000 people.

Kobane became a symbol of Kurdish resistance in January after a militant siege lasting several months was repelled. The Islamic State launched an apparent two-pronged offensive on Thursday after Kurdish fighters from the Popular Protection Units (YPG) cut off one of the militants' major supply routes near Raqqa.

"According to medical sources and Kobane residents, 120 civilians were executed by IS in their homes or killed by the group's rockets or snipers," said Rami Abdel Rahman, who heads the UK-based Observatory.
