Zagreb - Dinko Sakic, a former commander of Croatia's most notorious Nazi-era concentration camp during World War II, has died at age 86, news reports said Monday.

Sakic was in charge during May-October 1944 at the Jasenovac camp, where tens of thousands of Serbs, Jews and others died under the Ustasha regime, Croatia's
1941-45 Nazi puppet government.

He died late Sunday at a prison hospital in Zagreb, the capital, local media reported.
