A graffiti depicting German Chancellor Angela Merkel and European Central Bank (ECB) president Mario Draghi is seen on the fence around the site of ECB's new building under construction in Frankfurt am Main on June 6, 2013, 2013. The European Central Bank held its key rates unchanged, as widely expected, at its regular monthly policy meeting. The bank's new headquarter is to be finished in 2014.
