Officials said the man did not appear to be targeting Trump or others involved in the trial
Trump, speaking after talks with Palestinian President Mahmoud Abbas in the town of Bethlehem in the occupied West Bank, said the United States stands in "absolute solidarity" with the British people.
"I extend my deepest condolences to those so terribly injured in this terrorist attack, and to the many killed and the families, so many families of the victims," Trump said. "So many young, beautiful innocent people living and enjoying their lives murdered by evil losers in life."
