Secretary of State Rex Tillerson issued a statement this afternoon following attacks which took place in the vicinity of the UK Parliament building in London earlier today. 

"On behalf of the United States, I express, our condolences to the victims and their families. The American people send their thoughts and prayers to the people of the United Kingdom. We condemn these horrific acts of violence, and whether they were carried out by troubled individuals or by terrorists, the victims know no difference," Tillerson said.
