Pro-Russian separatists in eastern Ukraine have seized a bus carrying international military observers, Ukraine’s interior ministry says.
Negotiations were under way to secure the release of the observers, seized near the town of Sloviansk, it added.
Western leaders earlier announced they were debating fresh sanctions against Russia over its alleged failure to help de-escalate the crisis in Ukraine.
Russia has accused the West of wanting to “seize” Ukraine.
Moscow has tens of thousands of troops stationed along its side of the border with Ukraine and pro-Russian separatists have been occupying key buildings in a dozen eastern towns, defying the central government in Kiev.
Divers searching a sunken passenger ferry off South Korea found 48 bodies in a single room on the vessel meant to accommodate 38 people, officials say.
The group was crammed into a dormitory and all were wearing lifejackets, a South Korean Navy officer said.
Some 183 bodies have been recovered from the Sewol, but scores of people are missing, presumed drowned.
The head of the operation to retrieve bodies said on Friday he had “no idea” how long the ship search would take.
There were 476 people on board, with many trapped inside as the ferry listed and sank within two hours of distress signals being sent. A total of 174 passengers were rescued.
Many of those who died or are presumed dead were students and teachers from Danwon high school, south of Seoul.
