Border tensions rise as Hungary releases people smugglers and Austria tightens security.

Austria has increased security along its border with Hungary after Budapest released hundreds of foreign prisoners convicted of people smuggling, giving them just 72 hours to leave the country. Austria's government has asked Hungary for explanations, calling the decision to release several hundred convicts a direct impact on its security. Hungary's officials said the release of the convicted people smugglers, all of whom are foreign nationals, was intended to free up space in Hungarian prisons and unburden taxpayers. Austria criticised the decision as a contradiction to Hungary's own stance on migrants.
