It's the third week of attacks by the US and Israel on Iran, as well as Iranian retaliation across the region. It's not clear exactly how many lives the conflict has cost. The US‑based Human Rights Activists News Agency estimates at least 1,800 deaths in Iran alone. There have also been the deaths of at least 13 US troops, more than 850 people in Lebanon, and civilians in Israel and across the Gulf. The death toll looks set to rise, with no immediate end to the war in sight.
