claimed by the Chabad-Lubavitch group adds to tensions between Moscow
and Washington, which have seen ties deteriorate over human rights and
security issues since Putin's return to the Kremlin in May.
"The Schneerson Collection belongs to Russia,"
Putin said in a grand new Jewish museum in Moscow, in referring to
texts held in Russian libraries and archives, some of them confiscated
by the Soviet Union from Nazi forces during World War Two.
