A 16-year-old girl who’d just been savagely stabbed in the head made a desperate call to 911 as she lay bleeding to death on a Brooklyn street corner, police sources said.

Kyanna Thomas, 16, was attacked in the head at the corner of McDougal Street and Saratoga Avenue in Bedford Stuyvesant early this morning, cops said.

The Rosedale, Queens, girl was rushed to Interfaith Hospital, where she was pronounced dead.

Police have no suspects at this time.
