Taylor Swift says she's filled with "rage and grief" in a rare social media post after the Texas primary school shooting.
The 32-year-old US pop star, who hasn't posted on Twitter since January, told her 90 million followers that the shooting, which saw 19 children killed, had left her "so broken".
Two adults were also killed in the shooting spree.
"Filled with rage and grief, and so broken by the murders in Uvalde. By Buffalo, Laguna Woods and so many others," Swift added of other recent shootings in the US.
"By the ways in which we, as a nation, have become conditioned to unfathomable and unbearable heartbreak."
