"The office of Consulate General of the Republic of Poland in Lutsk was hit by a rocket-propelled grenade at 12:08 a.m. on March 29. A group of about 100 people attempted to block Lviv-Rava-Ruska highway at 10:15 a.m. on the same day.
"The rally was planned to last until 10 p.m. while its participants were instructed to show resistance to law enforcers.
"The time and manner of the events suggest that both provocations were coordinated in order to exacerbate the Ukrainian-Polish relations and the situation in the country.
"The law enforcers unblocked the highway and interviewed 92 detainees. Two organizers were served indictments. The court decides whether to impose pre-trial detention on them.
"The Security Service investigators established that the malicious plot of the Russian secret services was implemented by leader of Nazhdak extremist organization Mykola Dulskyi, who is hiding in the territory of the Russian Federation. The Ukrainian law enforcers put him on wanted list for murder threat," the SBU said.
