US-Israel Strike Pasteur Institute in Iran on Day 35; Iran Death Toll Reaches 2,076

On Day 35 of the US-Israel war on Iran (April 3, 2026), US and Israeli forces struck the century-old Pasteur Institute — Iran's premier biomedical research center near Tehran — along with a military-logistics bridge and two steel plants supplying dual-use materials for Iran's weapons program. The strike on the Pasteur Institute drew widespread international condemnation, with scientists and public health officials protesting the targeting of civilian research infrastructure. Iran's foreign ministry accused Israel and the US of 'deliberately targeting scientific heritage.' The cumulative Iranian death toll since February 28 reached at least 2,076 killed and 26,500 wounded, with over 600 schools damaged across Iran. The Strait of Hormuz remained closed; no commercial tanker traffic was reported on April 3. The intensifying Iran war continued to divert international attention from Gaza, where Phase 2 ceasefire negotiations remained completely stalled and humanitarian conditions were deteriorating sharply.
