The three former presidents warned against "dangerous recipes" proposed by some politicians and said law-enforcement agencies should look into separatist calls, allegations about violations of the rights of the Russian-speaking population, as well as the "fomenting of hostility" between Ukraine's regions and cases of "open disrespect of Ukraine's state symbols."
Pro-Russian activists have held rallies in Crimea following President Viktor Yanukovych's ouster, raising the Russian flag on government buildings.

Hundreds of pro-Russian activists are protesting against Ukraine's new government, which came to power after antigovernment demonstrations toppled President Viktor Yanukovych on Saturday.
The protesters are demanding a return to the Crimean Constitution of 1992, which gave the peninsula more autonomy.
They also want a referendum on Crimea's legal status.
Meanwhile, hundreds of Crimean Tatars who support the new leadership in Kyiv and who oppose Crimea's possible separation from Ukraine are also rallying.
The Crimean parliament is scheduled to discuss the crisis at an extraordinary session on Wednesday.
Russian lawmaker Leonid Slutsky, who visited Crimea this week, said earlier that Russia is ready to carry out "any measures to defend the interests of its compatriots residing in Crimea."
