Children's Hospital under siege
Tuesday, 11:45 p.m.
Late Tuesday, Gov. Blanco spokeswoman Denise Bottcher described a disturbing scene unfolding in uptown New Orleans, where looters were trying to break into Children's Hospital.
Bottcher said the director of the hospital fears for the safety of the staff and the 100 kids inside the hospital. The director said the hospital is locked, but that the looters were trying to break in and had gathered outside the facility.
The director has sought help from the police, but, due to rising flood waters, police have not been able to respond.
Bottcher said Blanco has been told of the situation and has informed the National Guard. However, Bottcher said, the National Guard has also been unable to respond.
