Babchenko said the reaction by state officials and state media to his remarks was meant to send a signal to Russian society that "we must be in one line; we must express sadness; we must appear sad - and anyone who doesn't must be destroyed".
According to the SBU, the Russian special services ordered the murder of Babchenko and paid an unnamed Ukrainian citizen, $40,000 to organize the murder.
However, he turned up at the presser today with Ukrainian officials who said the country's Security Service faked the journalist's death in an attempt to gather evidence on Russian agents in Ukraine.
Police in Kiev said Babchenko's wife found him outside their apartment.
MSNBC foreign correspondent Matt Bradley said the operation was "meant to catch people who were trying to kill" Babchenko. Arkady Babchenko was living in Ukraine since February 2017 after facing threats in his country.
Babchenko is a famous Russian journalist and a critic of the regime of Russian President Vladimir Putin.
Babchenko, a prominent war correspondent, is extremely critical of Russia's annexation of Crimea, and was forced to flee Russian Federation in February 2017 because of threats to him and his family.
The 41-year-old is one of Russia's best-known war reporters.
Kiev police reported on Tuesday evening about an attack on Babchenko, in which he was allegedly gunned down. They said that one arrest had been made so far.
However, the journalist has appeared at a news conference in Ukraine.
He fled Russia in 2017 after provoking a scandal in a Facebook post that expressed indifference over the deaths of a military choir and other passengers aboard a Russian plane that crashed en route to Syria.
In Ukraine, Babchenko worked for the Crimean Tatar television network, ATR, and reported frequently on Russia's support for separatist militants in eastern Ukraine.
Babchenko also spoke about his time fighting in Chechnya, describing the philosophy of hate that he and his fellow soldiers were exposed to-that all Chechen men age 10-60 were enemies that Russian soldiers should "Kill, kill, kill". He had been critical of the Kremlin in recent years.
