Security guards scrambled to restrain a man as he held aloft a sign reading “Nuclear weapons ban treaty” ahead of the Russian and US Presidents arriving to their post-summit press conference.
Shock video showed the suited man, writer and activist Sam Husseini being bundled out of the room after trying to catch the attention of the world’s media as they waited for Vladimir Putin and Donald Trump.
The protesting journalist can be seen standing up while trying to unfurl the small paper banner while resisting pressure from a solo security guard.
After a small scuffle the man is restrained by the security and ushered out of the room by reinforcements.
Officials had reportedly asked the reporter to leave the room earlier, and at that point he left peacefully, according to CNN’s Jim Acosta.
However, he then suddenly returned and then had to be forcibly removed after revealing the hand-written sign.
The man identified himself as a US journalist from The Nation – A US publication focussing on political news, comment and analysis.
Media are gathered in Helsinki for the press conference which was due to begin at 2.50pm UK time. However, the appearance has been delayed.
The pair met in the Finland capital this morning and posed for photographs.
Mr Trum told press he was looking forward to building an “extraordinary relationship” with Russia after two years of problems.
On the agenda for talks were “everything from trade to military, to missiles:, from Mr Trump. The US president said they would also be discussing “their joint friend” President Xi of China.
