Nov 8 (Reuters) - Activist investor Carl Icahn, who has been waging a bitter battle against Occidental Petroleum Corp's board over its $38 billion acquisition of Anadarko Petroleum, cut his holdings in the oil and gas producer by nearly a third, according to an open letter to shareholders he released Friday.
Icahn sold 10 million shares and now holds 23 million shares, valued around $900 million, he said. He had owned a $1.6 billion stake in Occidental as of May 30. (Reporting by Jennifer Hiller, Editing by Franklin Paul)
