Dutch and Australian governments are sending military presence with crash investigators to keep the MH17 crash site secure, dubbing the effort a "police-led humanitarian mission."
Search crews will send a sub deep into the Indian Ocean on Monday for the first time to try to determine whether signals detected by sound-locating equipment are from the missing Malaysian plane's black boxes, the Australian head of the search said.
The search area for the lost Malaysian jetliner moved 1,100 kilometers (680 miles) to the northeast on Friday, following a new analysis of radar data, and a plane quickly found objects that a ship set out to investigate. The search area has changed several times since the plane vanished as experts analyzed a frustratingly small amount of data from the aircraft, including the radar signals and "pings" that a satellite picked up for several hours after radar contact was lost.
