(CNN) --
ISIS moved closer to seizing Kobani on Sunday as militants entered the
southeastern edge of the Syrian city and street-to-street fighting began, a
fighter and a media activist inside the city told CNN.
The city's
defenders were looking for ways to escape the Kurdish stronghold strategically
located near the Turkish border, the fighter said.
"It's
the last chance to leave," the fighter said. The fighter and media
activist requested their names be withheld for security reasons.
