Czech Prime Minister Bohuslav Sobotka has called a meeting of the National Security Council on Sunday evening to assess the latest developments and potential threats to the security of the country, Radio Prague reported.

The illegal migrants' crisis as well as terrorist attacks in three countries on Friday are the two main issues to be addressed.

Czech has already increased checks of travelers along railway and other major routes and could reinstate full border controls with the help of the Czech Army should the country see a dramatic rise in the number of illegal migrants.

Currently, countries such as Greece and Italy are bearing the brunt as entry points for illegal migrants from North Africa and the Middle East.

Security at key sites, including airports in the Czech Republic, have meanwhile been boosted in response to terrorist attacks in three countries including Tunisia on Friday which killed dozens of people including both vacationers and locals.
