US readies further sanctions on Russia

The crisis escalated when armed pro-Russian separatists in the eastern city of Slaviansk seized a bus carrying international mediators. A separatist leader said the mediators were believed to have a Kiev āspyā among them.
The White House said US president Barack Obama and European allies all felt that Russia had escalated tension in eastern Ukraine, where pro-Moscow separatists have refused to leave official buildings they have occupied. But it gave no details of what the sanctions might be, or when it planned to enact them.
