“I think that counter-terrorism cooperation between Russia and the United States is not only possible and desirable, it is necessary,” Putin said.

According to him, this common threat is not becoming less dangerous than 20 years ago.

The Russian leader added that an expansion of the threat of terrorism is currently being observed, which is of a global nature. 

Putin stressed that it is possible to effectively fight terrorism only by "uniting efforts."

Earlier, Deputy Chairman of the Russian Security Council Dmitry Medvedev said about the importance of cooperation between the Russian and American sides in the fight against terrorism.
