Tehran [Iran], July 5 : Iranian President Masoud Pezeshkian on Saturday (local time) condemned Israel's actions in the region and criticised the United States for supporting them, alleging that the region has witnessed the targeted killing of intellectuals, scientists and other influential figures, IRNA reported. Speaking at the international conference "Imam Khamenei; The Eternal Leader of Resistance" in Tehran, he also questioned the effectiveness of international institutions, saying they had failed to prevent such actions despite claiming to uphold human rights, IRNA reported. Pezeshkian said that if "Muslim nations acted collectively, conflicts and humanitarian crises in Gaza, Lebanon and Palestine could not continue unchecked." He also warned that divisions among Islamic sects and ethnic groups create opportunities for external actors to exploit regional tensions, as reported by IRNA.
