The latest news on the crisis in Ukraine, plus a look at the technology aiding in search for Flight 370.
(CNN) – Diplomats meeting for emergency talks on the crisis in Ukraine issued a joint statement Thursday aimed at de-escalating the tensions and ensuring the security of all Ukrainians.
The pact calls for all illegal armed groups to be disarmed, all illegally seized buildings to be returned to their legitimate owners and all occupied public spaces to be vacated. It promises amnesty for protesters who leave buildings and give up their weapons, apart from those convicted of capital crimes.
But the agreement means little to protesters on the ground, reports CNN's Nick Paton Walsh. CNN's Elise Labott also weighs in on the ongoing crisis, in the video above.

Jindo, South Korea (CNN) – Anguished relatives of missing South Korean ferry passengers waited for answers Thursday as rescuers fought bad weather, murky water, darkness and time to find a way deep into the capsized ship.
Authorities believe 276 people - many of them high school students on a field trip - may remain trapped inside the five-story ship. At least some, authorities say, could still be alive more than a day after the ship rolled over.
Meanwhile, the ferry's captain is facing mounting questions about the incident.
Among other things, authorities are investigating the possibility the ship was off course when it ran into trouble, reports that few of its lifeboats made it into the water and reports that the captain was among the first to escape, according to Kim Soo Hyeon, the chief of South Korea's Yellow Sea Maritime Police Agency.
Under South Korean maritime law, the captain is supposed to stay with the ship, CNN's Kyung Lah reports.

(CNN) – The captain of the South Korea ferry that capsized with hundreds of passengers on board faces questions amid reports the ferry may have been off course, and turned quickly.
The passengers, many of them teenagers, were told to stay on board, while the captain left the ship.
There is no set protocol for captains and ships in distress, says Adm. Thad Allen (Ret.), former commandant of the U.S. Coast Guard.
