International human rights campaigners, United Nations experts, journalists, and anti-war activists marked the 25th anniversary of the September 11, 2001 attacks on the US by paying tributes to the thousands of lives lost on that day while condemning what followed: an unparalleled expansion of state surveillance, crackdowns on dissent, arbitrary detention, torture, and catastrophic wars that cost trillions of dollars and millions of lives.

Mourning the lasting impact of “those horrific acts of violence” perpetrated in the US a quarter-century ago, a group of more than 40 UN experts said in a joint statement on Friday that “we equally acknowledge the millions of other victims worldwide of terrorist attacks, excessive counter-terrorism responses, and conflicts in the name of countering terrorism.”
