How to interpolate a string in Jade & Pug?

Question

JavaScript

Here is some block with img googleapi. How to interpolate a string using the pug preprocessor.
I tried the method below - it does not go out, it outputs to the browser as it is written, without conversion.

.panel-body
    img.img-responsive.img-rounded(src="http://maps.googleapis.com/maps/api/staticmap?center=#{location.coords.lat},#{location.coords.lng}&zoom=17&size=400x350&sensor=false&markers=#{location.coords.lat},#{location.coords.lng}&scale=2")
