Russia's Federal Security Service security service has arrested members of a Ukrainian military intelligence network that it claims was planning “a series of high-profile sabotage and terrorist acts” in Russian-annexed Crimea.
In a statement released on Wednesday, the FSB said the group had planned attacks against officials installed by Russia including local governor Sergei Aksyonov.
It said it had seized explosives identical to those used to attack railways in the peninsula in February.
In a statement, Mr Aksyonov said the same group was behind both alleged incidents.
He said, without providing evidence, that there was no doubt that the Ukrainian government was responsible.
“There is no doubt that the people who ordered these crimes are in Kyiv,” Mr Aksyonov said on his Telegram channel.
The FSB said the same group had carried out a railway sabotage in February.
Russia seized Crimea from Ukraine in 2014 and used it as one of the launch pads for its military invasion of Ukraine in February 2022.
Russia launched a third round of night attacks on Kyiv in six days, authorities in the Ukrainian capital said on Wednesday, with a drone hitting a building in the Dnipropetrovsk region as Moscow steps up attacks on its neighbour.
Separately, Russia's Foreign Ministry said on Wednesday that proposed talks between Russia, Ukraine and Turkey on the Black Sea grain deal on May 5 have not yet been agreed.
Earlier on Wednesday, Turkish state-owned Anadolu news agency quoted Turkey's Defence Minister Hulusi Akar as saying the grain deal would be discussed at a meeting in Istanbul.
But Russia's state-owned news agency RIA quoted the Foreign Ministry as saying of the proposed talks: “The question has not yet been agreed.”
Russia has repeatedly cast doubt on the renewal of the Turkish-brokered grain deal, which was signed in July last year and regulates Russian and Ukrainian agricultural exports on the Black Sea.
Ukrainian President Volodymyr Zelenskyy arrived in Finland's capital, Helsinki, for a one-day Nordic summit on Wednesday.
Mr Zelenskyy is expected to meet four Nordic prime ministers at the residency of the Finnish President Sauli Niinisto to discuss their support for Ukraine.
The Nordic countries — Finland, Sweden, Norway, Denmark and Iceland — have largely rallied around Ukraine following Russia’s invasion.
Those meeting in Helsinki are Swedish Prime Minister Ulf Kristersson, Norway’s Jonas Gahr Store, Danish Prime Minister Mette Frederiksen, Iceland’s Katrin Jakobsdottir and the Finnish President.
Mr Niinisto said the summit would discuss Russia’s aggression in Ukraine, the Nordic countries’ continued support for Kyiv and its relationship with the EU and Nato, and the country's peace initiative.
“There is still an urgent need for military support to ensure that the Ukrainians stand as strong as possible in the fight against Russia,” said Ms Frederiksen.
“We must help rebuild Ukraine and keep alive the hope for a normal everyday life and a just future on the other side of the war.”
