About 700 litres of diesel fuel from a tractor trailer's fuel tanks spilled into a south Ottawa ditch on Tuesday morning after a minor collision, firefighters say.

The crash happened near the intersection of Hawthorne Road and Stevenage Drive, between Walkley and Hunt Club roads, at about 7:20 a.m.

Firefighters and a hazardous materials team were dispatched to the scene to try to contain the spilled fuel before it reached sewer drains, according to a media release issued Tuesday.

Crews will remain at the intersection until city workers arrive.

No one was injured.
