More than 900 Russian citizens were denied entry from year-start, says a speaker for the State Border Guard Service of Ukraine, Oleh Slobodyan.

"Higher alert status at the border is still in force. Over 900 Russian citizens have been refused entry to Ukraine since the beginning of the year," he told UNIAN.

Grounds for refusal were mainly a failure to confirm the purpose of the trip, the excess of the period of stay in Ukraine during previous trips or violation of law concerning visits to the temporarily occupied Crimea, Slobodyan clarified.

As UNIAN reported earlier, after Russian forces attacked three Ukrainian navy boats near the Kerch Strait in the Black Sea on November 25, Ukraine from November 26 to December 26 introduced martial law in 10 regions - areas located along the Russian border and the Transnistrian section of the Ukrainian-Moldovan border, as well as along the Black Sea and the Sea of Azov.

On November 30, Chairman of the State Border Guard Service of Ukraine Petro Tsyhykal announced that Russian male citizens aged 16 to 60 years would have limited access to Ukrainian territory in connection with the introduction of martial law.

In late December, the National Security and Defense Council extended the restrictive measures of the State Border Guard Service of Ukraine concerning the entry of Russian men into Ukraine.
