ABC News Anchor David Muir Reports from Iran (WATCH)

Reports to Air Across all Broadcast and Platforms Beginning Wednesday, February 20

ABC News anchor David Muir is on the ground inside Iran reporting for all ABC News broadcasts and platforms. Muir will report from the streets of Tehran revealing the effects of Washington's tightening sanctions on Iran.

Muir's reports come as Iran is expected to return to the negotiating table for crucial talks over its nuclear ambitions with the United States and others. Iran's Supreme Leader Ayatollah Ali Khamenei spoke out recently rejecting the idea of direct talks with the U.S. saying if America wants "to point the gun at the people of Iran and say, negotiate or we will shoot… you should know that the Iranian nation is not intimidated by these things." Iran will be a central issue discussed during President Obama's upcoming trip to Israel.

Muir's reporting will air throughout the week across all ABC News broadcasts beginning with " Good Morning America" and " World News with Diane Sawyer" on Wednesday, February 20. In addition he will anchor part of his broadcast, " World News with David Muir," from Iran on Saturday, February 23. His reporting will also be featured across ABC News Digital platforms.

David Muir is an Emmy award-winning anchor and correspondent for ABC News. He is the weekend anchor for the flagship ABC News broadcast "World News" and co-anchor of the ABC newsmagazine "20/20." Muir reports for ABC News from the scene of major news events around the world from Cairo to Jerusalem, from London to Beijing. Full bio here.
