Ukrainian security forces (SBUs) said they had captured a Russian military intelligence team. The team is being accused of attempting to kill a Ukrainian military spy ahead of the second round of presidential elections, which will be held on Sunday.

Vasyl Hrytsak, head of the SBU, told a press conference in the capital Kiev that 7 people were arrested and indicted, and an octave was arrested on Wednesday. Two are Russian citizens, the others are Ukrainians, accused of being part of the GRU, the Russian army’s intelligence service. Hrytsak said that in the past few days the group had placed a bomb under the car in which the Ukrainian secret agent was to climb. However, the bomb exploded before wounding one of the accused. The SBU also released a video of the incident.

Relations with Russia, which illegally annexed the Crimean peninsula in 2014 and supports pro-Russian separatists, are an important topic of the electoral campaign. The current president Petro Poroshenko, challenged by comedian Volodymyr Zelensky, proposes himself as the only person able to defend Ukraine from the Russian aims.
