Ukraine intelligence chief warns Russia 'our sources are everywhere,' including the Kremlin

Ukraine's intelligence service warned Russia that is has "sources" in the Kremlin as their war drags on with little progress from President Vladimir Putin's forces.

"We have sources in the Kremlin, but we need jets!" Ukraine's intelligence service wrote on Twitter on Monday, in a post that included a link to an interview from its chief Kyrylo Budanov.

Budanov told Coffee or Die Magazine in a recent interview via a translator that Ukraine's "sources are everywhere," saying his intelligence agency has people working for Ukraine in "the army, in the political circles, as well as administration of the president."

He told the magazine that Ukraine's access to its undercover sources and cyber intelligence allowed it to understand more about Russia's plans of attack and its military complex.

Budanov said told Coffee or Die Magazine that two examples of Ukraine's ability to rely on its sourcing to launch preemptive strikes on Russian targets are recent attacks on Russian convoys near Kyiv and the destruction of a Russian landing ship near Mariupol.

Budanov told the magazine that Ukraine has been able to keep an eye on Russia's military plans, and received help from Western allies like the US and UK.

"We have made considerable progress in cyber intelligence," he told the magazine. "We see the letters and all they write."

Since Russia invaded Ukraine on February 24, Putin's forces have failed to conquer the country and have largely stalled across multiple fronts.

In an attempt to find a cause of Russia's military blunders, Russian military's counterintelligence division has ordered a hunt for breaches in Russia's domestic security agency, the FSB, experts told Insider earlier this month.

Meanwhile, Russia's defense ministry has said it would pivot its focus to Ukraine's eastern Donbas region after being unable to break past Ukraine's fierce resistance.

Budanov said on Sunday that Russia is trying to split Ukraine in two and create a Moscow-backed state in the east and south of the country.
