Eugenia Tymoshenko: 'Very shocked by decision'
Ukraine has suspended preparations for a trade deal with the EU.
A government statement said the decision had been taken to protect Ukraine's "national security".
Hours earlier MPs rejected a bill that would have allowed jailed opposition leader Yulia Tymoshenko to leave the country - which the EU had demanded as a condition for the deal to proceed.
Her daughter Eugenia Tymoshenko told BBC News: "We are very shocked by this decision."
