"Är" twice in a sentence?

I saw this sentence on the Sveriges Radio website: "Proteströrelsens tält och barrikader är till stora delar fortfarande är kvar på Maidan." I feel like I have seen the use of "är" twice before, so I'm not sure if this is a typo, simply stylistic, or this if is common in Swedish.
Update: Ville ju säga "I have seen the use of 'är' twice in a sentence before"
Update 2: Jättetack, Wilma! Also, thanks for the bonus information. Skål!
