Lebanon's Parliament Speaker Nabih Berri said the outline nuclear agreement reached between Iran and the major powers last week has created a "new opportunity" for the region, citing the Saudi government's statement welcoming the agreement as an indication that the situation is changing. "Undoubtedly, the nuclear understanding has opened a door to the region and will definitely affect the situation in Lebanon," Berri told Lebanese newspaper Al-Mustaqbal, IRNA reported on Wednesday.
