Ukraine Bars 3 BBC Journalists From Entering Ukraine

Ukraine has barred a few dozen reporters, including three BBC journalists, from entering the country as an unspecified security threat.
Ukrainian President Petro Poroshenko late on Wednesday signed a sanctions list barring nearly 400 individuals from entering Ukraine, including BBC correspondent Steve Rosenberg and producer Emma Wells, both British, and Russian cameraman Anton Chicherov.
The decree which was published on the president’s website said the reporters and media executives on the list presented an unspecified “threat to national interests, national security, sovereignty or territorial integrity.”
It did not specify why the long-serving Moscow-based BBC journalists were singled out but a spokesman for the presidential administration said late Wednesday night that the Ukrainian Security Service would give an explanation on Thursday.
The BBC’s foreign editor, Andrew Roy, described the ban as “a shameful attack on media freedom.”
“These sanctions are completely inappropriate and inexplicable measures to take against BBC journalists who are reporting the situation in Ukraine impartially and objectively, and we call on the Ukrainian government to remove their names from this list immediately,” he said in emailed comments.
Also on the list of the banned journalists are Antonio Pampliega and Angel Sastre, two Spanish reporters who disappeared in Syria in July and are believed to have been kidnapped by the Islamic State group, and two reporters for Russian news agencies in South Africa and Turkey with no clear links to Ukraine.
The Russian news agency Tass on Thursday described the decision to blacklist three of its reporters, one based in Washington, D.C., one in South Africa and one in Moscow, as “odd” since two of the three journalists do not even cover Ukraine. …
The New York-based Committee to Protect Journalists said in a statement that it is “dismayed” by Poroshenko’s actions.
“While the government may not like or agree with the coverage, labeling journalists a potential threat to national security is not an appropriate response,” said the committee’s Europe and Central Asia program coordinator, Nina Ognianova.
