Ukraine's Interior Minister Arsen Avakov said he has information that terrorist attacks are planned in the largest cities of the country.

"According to the special services, destructive anti-Ukrainian forces will make several attempts to destabilize the situation in the country in the next few days. The Interior Ministry and the Ukrainian Security Service have information that terrorist attacks and provocations using firearms and explosive devices are being prepared in Kyiv, Kharkiv, Dnepropetrovsk, Lviv and some other cities of the country," he said on Facebook on Sunday.

In his message, the minister addressed the political forces and public organizations that plan to conduct rallies in the next few days.

"Your forms of protest are now extremely vulnerable to provocations and terrorist risks. You are responsible for people's safety. I am asking you to make all necessary decisions to prevent the slightest opportunity to use your constitutional right to protest as a cover of a terrorist attack," the interior minister said.
