A local US newspaper won a Pulitzer Prize for coverage of a mass shooting in its editorial office.
But there were no celebrations as the Capital Gazette of Maryland learned Monday that it had won the most prestigious award in American journalism.
The staff silently hugged in memory of five colleagues killed when an armed man broke into their office in June 2018.
Pulitzers also went to the New York Times and the Wall Street Journal for investigations of President Trump.
The Annapolis Capital Gazette won a special mention of the Pulitzer Prize for covering and daring one of the most deadly attacks on journalists in American history.
Pulitzer's board of directors awarded the quote with a $ 100,000 grant to promote journalism in the newspaper.
Employees John McNamara, Wendi Winters, Rebecca Smith, Gerald Fischman and Rob Hiaasen died in last summer's attack.
But the staff still managed to publish a newspaper scheduled the next day.
A man with a longstanding grudge against the Capital Gazette is accused of the attack. He pleaded not guilty last year.
The coverage of mass shootings led Pulitzers to two other local newspapers.
The Pittsburgh Post-Gazette received an award for the "immersive and compassionate" news of last October's attack on a Pennsylvania synagogue that killed 11 people.
And South Florida, Sun Sentinel, won a Pulitzer for its February 2018 mass filming services at Marjory Stoneman Douglas High School, which left 17 dead.
He received the recognition of the public service for "having denounced the shortcomings by the school authorities and the forces of the order before and after the deadly shooting".
The New York Times won an award for explanatory reports on finance and Trump's tax avoidance and another for the editorial staff.
The Wall Street Journal won the national award for reporting for discovering the president's secret profits at two alleged ex-lovers during his campaign.
The Washington Post has also won two Pulitzers for photojournalism in Yemen and for criticism.
The Reuters news agency received an award for its investigation into the killing of 10 Rohingya men in a village in Rakhine state in Myanmar.
