Mark Rothko painting at Tate Modern 'defaced'
A painting by artist Mark Rothko at the Tate Modern has been defaced by a small amount of black paint, a spokeswoman for the gallery has confirmed.
The London gallery said one of the artist's Seagram murals was defaced at about 15:25 BST.
Paintings by the Modernist painter, one of America's most important post-war artists, have sold for tens of millions of pounds.
The gallery was shut for a short period and then reopened.
Police are investigating the incident.
