U.S.-Iran nuclear talks show "some progress," no breakthrough in 5th round

The fifth round of nuclear talks between the U.S. and Iran in Rome ended Friday with "some but not conclusive progress," according to Oman's Foreign Minister Badr al-Busaidi, who is mediating between the parties.

Why it matters: In recent days the negotiations have hit a roadblock over the fact that Iran says it will only sign a deal that permits a domestic enrichment capability, and the U.S. has said enrichment is its red line.

• Israel has been making preparations to swiftly strike Iran's nuclear sites if U.S.-Iran nuclear talks break down in the coming weeks.
