Does jungle block line of sight?

Civilopedia says:

A unit cannot see a target if a blocking terrain object is between the two - a mountain or hill, for example, or a forest tile.

So does jungle count as "a blocking terrain object"? The description above doesn't mention it, but it doesn't feel conclusive. After all jungle is counted with hills and forests as rough terrain and in real life jungle is as much an obstacle as any forest.
