"Laboratory studies must be conducted to compare the genomes of the original virus and its distorted version to prove any deliberate alterations made," Jalali said.
Answering a question about the rumors that the COVID-19 has been developed as a biological weapon to negatively impact the Iranian and Chinese nations, he said, "Evidence may prove the virus outbreak as a biological attack on Iranian and Chinese economy."
He referred to the propaganda campaigns led by enemies about the outbreak of coronavirus and exaggerating the number of its victims as a means to frighten the Iranian nation and reducing their morale.
