GENEVA: The United Nations rights chief voiced alarm Tuesday at the Middle East conflict’s deepening impact on civilians, warning of the dangers of the seeming “tit-for-tat dynamic” between the warring sides. The United States and Israel began striking Iran on February 28, prompting waves of Iranian strikes across the Gulf. With hostilities intensifying, UN High Commissioner for Human Rights Volker Turk deplored the extensive attacks in residential areas, on health facilities, schools, cultural property and water and energy infrastructure.
