.....The State Department and the Office of the Director of National
Intelligence, both of which distributed the photographs to journalists
Sunday, did not indicate the source of the images, which were labeled
with the imprint of Digital Globe, a commercial satellite and
aerial-imaging company.
The
high-altitude images released Sunday “provide evidence that Russian
forces have fired across the border at Ukrainian military forces, and
that Russia-backed separatists have used heavy artillery, provided by
Russia, in attacks on Ukrainian forces from inside Ukraine,” according
to labels on the pictures provided by the U.S. government.
The
most recent photograph, taken Saturday, shows what are described as
“blast marks” from rocket-launcher fire on the Russian side of the
border and “impact craters” inside Ukraine.
