'Lock down' in Cardiff in preparation for Nato dinners
Central Cardiff was empty of its usual throngs of lunchtime shoppers and diners as the Nato summit security operation ramped up.
Many shops in the area were closed and people were comparing the business district to a ghost city.
Scores of world leaders and VIPs are expected for working dinners at Cardiff Castle and the nearby Royal College of Music and Drama later.
And protesters were expected to gather in the city centre for a march.
Police at security barriers helped keep a ring of steel around the castle.
