The chiefs of the UK's MI5 and MI6 have warned
Home Secretary Priti Patel against easing visa requirements for Ukrainian refugees, purportedly due to the risk they could include Daesh* militants and mafia-linked criminals, the
Daily Mail reports.
The newspaper quoted unnamed senior intelligence sources as saying that "no one disputes that this is a humanitarian tragedy, and that 99.9 percent of the refugees [from Ukraine] are genuine".
The source, however, cautioned that the British government "cannot just allow a complete open-door policy", adding, "Ukraine is a melting pot at the moment, and we have already been presented with fake passports".
They also advised against the Home Office's plans for an online visa system to receive Ukrainian refugees, asserting that such a system would be too vulnerable to hacking by alleged Russian security agents.
The claims come a few days after Patel told lawmakers in the Commons that the government plans to water down its rigid entry requirements for Ukrainian refugees.
This followed Roger Gale, a senior lawmaker from the Conservative Party, accusing Patel of misleading the parliament over a visa application centre (VAC) for Ukrainian refugees she said her department was setting up in the French port of Calais.
She claimed in an address to MPs on Monday that "we have staff in Calais, we have support on the ground. It is wrong to say we're just turning people back, we're absolutely not, we're supporting those that have been coming to Calais".
Earlier this week, UN estimates revealed that nearly 2.6 million refugees had fled Ukraine since the beginning of the Russian special military operation in the country on 24 February. Neighbouring Poland has so far received the most refugees, with others travelling to Hungary, Slovakia, Moldova, and Romania.
Russia launched
its special operation in Ukraine in order to demilitarise and de-Nazify the country, following a request for help from the Donetsk and Lugansk People's Republics, which saw weeks of intensifying shelling from the Ukrainian Army. The goal of the operation is to destroy Ukraine's military infrastructure with high-precision weapons, which do not target civilians, according to the Russian Defence Ministry.
