The Russian intelligence agency FSB says one of its employees and a soldier were killed in separate incidents described as foiled terrorist attacks.

The FSB said in a statement on Wednesday that its officer was killed late on Saturday outside the town of Armyansk on the de-facto border between Crimea and Ukraine when FSB officers engaged with what were described as Ukrainian saboteurs. The FSB said it found 20 bombs, ammunition and mines in the area of the attack.

The agency said two more groups of saboteurs tried to enter Crimea late on Sunday with Ukrainian artillery covering for them. The FSB said one Russian soldier died in the incoming fire.

Russia annexed the Crimean peninsula in 2014 following a hastily called referendum.
