DUBAI (Reuters) - Iran’s daily tally of coronavirus deaths hit a record high of 434 on Sunday, the health ministry announced, and the head of a top medical body said the actual toll was at least three times higher than the official count.The deaths, announced by Health Ministry spokeswoman Sima Sadat Lari on state TV, take the official toll to 35,298 in the Middle East’s worst-hit country. She said the number of confirmed coronavirus cases increased by 7,719 to 620,491. The head of Iran’s Medical Council, Mohammadreza Zafarghandi, doubted the accuracy of the official toll and warned that Iran had reached a “catastrophic mortality rate”, the Students News Agency ISNA reported on Sunday. “The official death toll is only based on the number of registered patients,” Zafarghandi told ISNA. “Through field surveys in hospitals and cemeteries, our Council has obtained a figure at least three times higher than the official death toll.”
