By Yuka ObayashiTOKYO, Aug 6 (Reuters) - Oil prices slipped on Thursday as investors assessed whether progress in Iran-Oman talks could pave the way for a U.S.-Iran peace deal to ‌end the five-month war and reopen the Strait of Hormuz. Brent crude futures fell 37 cents, ‌or 0.5%, to $79.08 a barrel by 0024 GMT. "Some selling pressure emerged following reports that talks between Iran and Oman are making progress," said Yuki Takashima, economist at Nomura Securities. Meanwhile, Yemen's Iran-aligned Houthis said on Wednesday they had launched a missile attack ‌on a Saudi oil tanker off the coast of the ​kingdom's Red Sea port city of Yanbu and another missile ​attack on a Saudi oil tanker in ​the Gulf of Aden. Separately, U.S. crude stocks rose as refineries eased processing slightly and imports edged higher, data from the Energy ​Information Administration showed on Wednesday.
