In a post retweeted by @hey_itsmyturn from @TheStudyofWar (CTP-ISW), it reports that Iran has conducted five waves of ballistic missile attacks targeting Israel since the last data cutoff. Iran launched one missile in three of the waves, two missiles in one wave, and a 'small' number in another wave. An Iranian ballistic missile fragment struck an industrial zone in Ne'ot Hovav, southern Israel, causing a large fire. The industrial zone houses at least 19 chemical companies. Israel advised residents to stay inside to avoid toxic chemicals. An Iranian missile also struck an open area in Beer Sheva, causing at least 11 injuries from flying objects due to the shockwave. Iran also attacked Gulf countries: missiles struck two aluminum factories in UAE and Bahrain. The Emirates Global Aluminum CEO said the facility sustained 'significant damage.' This company supplies about 4% of the world's aluminum. These strikes follow combined force strikes on Iranian steel factories on March 27 and 28. The combined force continued to target Iran's defense industrial base, striking multiple drone, missile, and air defense production sites in Tehran. The combined force also targeted Iranian internal security institutions. An OSINT account (@hey_itsmyturn) reported airstrikes near the IRIB complex in Tehran. IRIB is the state broadcaster used for propaganda. The IDF has previously struck IRIB headquarters. The source noted IRGC sites near the complex. The IDF said Iran has moved security headquarters to mobile structures in recent days, likely due to concerns about airstrikes. The IDF struck several temporary headquarters in Tehran on March 28. The combined force killed senior Iranian officials: Iranian media reported airstrikes killed the head of research at SPND in Borujerd, Lorestan Province, on March 28. SPND played a leading role in Iran's nuclear weapons research program before 2003.
