NPR's Louisa Lim reports that North Korea fired the missiles in defiance of international sanctions. She filed this report for our Newscast unit:

"North Korea launched two guided missiles this morning and a third in the afternoon, according to South Korea's defense ministry — all landed in waters off the eastern coast of the Korean peninsula."

Six years ago, the FBI took on a challenge: To review what it called cold-case killings from the civil rights era. The investigation into 112 cases from the 1950s and 1960s is winding down, and civil rights activists are weighing the FBI's efforts.

The review comes with word this week of the death of a man who'd been named, by a newspaper investigation, as a possible suspect in one notorious case.

The Case

It's been a long slog already for the bipartisan immigration overhaul proposed by the Senate's Gang of Eight.

The legislation has been the target of more than 300 amendments during days of debate and votes by the Senate Judiciary Committee. But while the bill has largely held its own so far, its prospects for getting through Congress remain uncertain.

In Judiciary Committee Chairman Patrick Leahy's view, the immigration overhaul is "moving very well."

"It's moving a lot faster than people said it would," says Leahy, a Vermont Democrat.
