June 21 (Reuters) - Iran's Tasnim news agency, citing a source close to the negotiating team, reported on Sunday that the Strait of Hormuz would not be reopened as long as a ceasefire in Lebanon was not respected. The source said the waterway would also remain closed until waivers allowing the sale of Iranian oil were issued. (Reporting by Eman Abouhassira, Editing by Louise Heavens)
