"The extremely aggressive probing of our air space by Russian aircraft is an issue of concern to us," British Foreign Secretary Philip Hammond told a committee of British lawmakers.
According to him, NATO countries should unite in response to the changes that have occurred in the relations between Russia and the Alliance.
"It is entirely appropriate for NATO countries in particular to work together to respond to what is a change of Russia's dealings with NATO and indeed the non-NATO European countries," Hammond said.
Mr Hammond said he did not accept this, saying the government had to be "careful not to play all the cards in our hand and leave ourselves in a position where further Russian aggression can't be responded to," BBC reports.
He said the UK was not taking action unilaterally, and stressed the importance of having "solidarity" in the response across Europe.
Recall, the Russian military aircrafts are more frequently registered in the air space of Europe.
In particular, the NATO Secretary General Jens Stoltenberg said that the Alliance fighters have scrambled more than 400 times to intercept the Russian Federation military aircrafts.
At the same time, he noted that the Russian warplanes act aggressively but basically do not violate the airspace.
