Last week, Ukrainian authorities, in coordination with the U.S. Central Intelligence Agency and Georgia's Interior Ministry, detained Al-Bara Shishani, a top IS commander.

The Georgian national had served as a deputy to Abu Omar al-Shishani, the man the Pentagon has described as the militant group's "minister of war."

After the latter was killed in 2016, Al-Bara Shishani fled to Turkey and in 2018 used a fake passport to enter Ukraine, where he continued to coordinate IS activities, Ukraine's State Security Service (SBU) said.

He was detained in Kyiv region near a private home where he resided, the SBU said.
