Two police officers were injured today after a man detonated explosives inside a Kiev courthouse, Ukrainian authorities said. The man had previously barricaded himself inside a courthouse.

The two police officers, members of a special rapid reaction unit of the security forces, were injured trying to immobilize the man inside the court.

Ukraine’s interior minister named the attacker as Ihor Khumenyuk and said he was being brought before the court as a suspect in connection with the deaths of four Ukrainian national guardsmen in 2015.

After the hearing, Ihor Klimenko continued, the man locked himself in a toilet and threw an explosive device at the two guards. Two explosions were heard at the Shevchenkivskyi district court in central Kyiv, while the area was cordoned off and ambulances rushed to the scene.

As officers fired into the air to prevent him from leaving the building, the man barricaded himself inside another room, Klimenko said. The man refused to negotiate with the officers and threw another device at the two officers who were injured.

Klimenko said the man was killed on the spot, without elaborating. An investigation is underway to determine how the man came into possession of explosives at the courthouse. The minister, in his announcements, made no connection between the attack and the war in Ukraine.

In Kiev, security measures have been tightened since the start of the Russian invasion of Ukraine in late February 2022, and a night-time curfew is in effect.
