Los Angeles: Chat show host Ellen DeGeneres, actresses Olivia Munn, Eva Longoria and boyband Maroon 5, among others, took to social media to express their shock and sadness over a mass shooting at the Umpqua Community College in Oregon on Thursday.
A 20-year-old gunman opened fire, killing at least 10 people and injuring 20 others before police shot him dead in the latest incident of mass shooting to rock the country.
Local authorities, who are investigating the case, offered no immediate word on his motive.
As the shocking news of another US campus shooting incident unfolded, stunned celebrities took to Twitter to express their feelings.
DeGeneres wrote, "I can't imagine what the families of UCC are going through. The world is rising up to hold you in the light. I hope you can feel our love."
Munn said, "Sending my love and prayers to the victims and families of UCC", while Longoria posted, "My hearts and prayers for those in Oregon."
Singer Leann Rimes tweeted, "Reading the news about the #OregonShooting horrific! My heart goes out to the victims and their families."
Sara Bareilles added, "Oh God. My head is reeling. I'm so sorry and so sad for the victims in Oregon. My prayers are with you."
Maroon 5, who are currently on tour in New Zealand, also took the time to pay tribute to the lives lost, posting: "Our hearts go out to the victims of the #UCCShooting, all the way from here in New Zealand."
Fashion designer Nicky Hilton wrote, "In the 274 days of 2015, there have been 293 mass shootings. Today's shooting in Oregon marks the 294th. This must stop". The Oregon massacre is the latest school shooting to rock America following similar gun atrocities at Sandy Hook Elementary School in Newtown, Connecticut in 2012, and Arapahoe High School in Denver, Colorado in 2013.
