Celebrities have used social media to express their upset and anger following a shooting in Las Vegas on Monday, which is understood to be the most deadly in modern US history.
At least 58 people were killed and over 500 were injured after a lone gunman opened fire on a country music festival in the city.
Singer Ariana Grande, whose Manchester concert was the target of a bombing attack in May, described the incident as "terrorism", writing on Twitter that "love, unity, peace [and] gun control" were needed.
Many other celebrities also called for tougher gun ownership restrictions.
Tagging US President Donald Trump and Speaker of the House of Representatives Paul Ryan, singer Lady Gaga encouraged politicians to "act quickly".
"Blood is on the hands of those who have power to legislate," she tweeted.
"Sensible gun control NOW," actress Alyssa Milano tweeted, adding her voice to the outpouring of grief.
Singer Rihanna described the event as a "horrific act of terror".
Other celebrities simply expressed sorrow for those affected.
Singer Taylor Swift, who found fame in the country music scene, tweeted there were "no words to express the helplessness and sorrow [her] broken heart feels for the victims in Vegas and their families".
