After initially denying responsibility for last month's death of a United Nations staff worker in central Gaza, Israel's military has acknowledged that it killed Marin Valev Marinov when it attacked a U.

It was the second time in a week that Israel’s military, after an internal investigation, reversed an initial denial of its role in a deadly incident.

Israeli tank fire killed a UN worker in Gaza last month, according to initial findings from an investigation released Thursday by Israel's military, which initially denied operating in the area.
