Iran's highest leader has demanded that international economic sanctions against his country end as soon as a final agreement is reached on Iran's nuclear development program.

Ayatollah Ali Khamenei spoke on Iranian television Thursday. He said that a framework agreement with the West does not guarantee a completed deal will be reached. Mr. Khamenei also said he is "neither for nor against" the agreement reached last week by Iran and six world powers. He said that deal is non-binding.

Iranian President Hassan Rouhani made similar comments earlier in the day. The president said Iran would not accept any final deal unless all international sanctions were cancelled.

Feidin Santana took the wireless telephone video of a white police officer shooting an unarmed black man. Mr. Santana said he had at first considered removing the video from his phone. He told NBC News that the police officer, in his words, "had control of the situation." He also said the officer used an electronic stun gun on the man, Walter Scott.

Mr. Santana began recording the incident when the 50-year-old Walter Scott began running away from the police officer. The officer aimed his gun and fired eight shots at Mr. Scott. He fell about 9 meters away from the officer. Mr. Santana said he gave the video over to Scott's family after reading the police's version of the events in the news.

On Tuesday, officials charged Michael Slager with murder.
