Barrier-breaking US comedian, activist Dick Gregory dead at 84

US comedian and civil rights activist Dick Gregory, who broke barriers as a performer in the era of segregation and challenged racism through searing humor, died Saturday night, his family said. He was 84.

In a Facebook post, Christian Gregory did not give the cause of death but said his father started feeling ill on August 9, and was admitted to a hospital on August 12. He died in Washington.

"A life well-lived but heavily sacrificed, has definitively taken its toll," the son said. More details were to be released in the coming days.

Gregory performed in the country's top clubs in the early 1960s and was not shy about confronting his white audiences with the realities of racism.

"A Southern liberal?" he once said, according to the Washington Post. "That's a guy that'll lynch you from a low tree."

Or his line about trying to order at a restaurant in the segregated South and being told by the waitress, "We don't serve colored people here."

Gregory replied, according to the New York Times, "That's all right, I don't eat colored people. Just bring me a whole fried chicken."

Gregory was credited with laying the groundwork for black comics who would come later, particularly Bill Cosby and Richard Pryor.

Later on in the 1960s, he became a fervent front-line activist on various racial and social causes. He staged a modest write-in campaign for president in 1968 that garnered fewer than 50,000 votes.

In later decades, he became known variously as a prodigious hunger striker, conspiracy theorist, diet guru and health food advocate.

Prominent Americans paid tribute to Gregory late Saturday.

"He taught us how to laugh. He taught us how to fight. He taught us how to live. Dick Gregory was committed to justice. I miss him already. #RIP," civil rights activist the Reverend Jesse Jackson said.

"Dick Gregory, Truth teller, make you fall on your face laughing Comedian, health man before it was cool & crazy expensive unapologetic About being black in America Dick Gregory has passed away, Condolences to his family and to us who won't have his insight 2 lean on," actress Whoopi Goldberg tweeted.

Gregory's death came at a time of anguished national debate over racial relations, a week after a suspected neo-Nazi at a white supremacist rally in Virginia drove his car into a crowd of counter-protesters, killing a woman.

President Donald Trump defended some far-right protesters at the rally as "very fine people."

Gregory, whose Instagram account was checkered with promotions for his many club appearances around the country, touched on the issue in a post from March.

"As I approach my 85th revolution around the sun this year, I wonder why has it been so difficult for humankind to be kind. So difficult to be loving and lovable," Gregory said.

"For my militant brothers and sisters, please don't misconstrue loving and lovable to be weak or submissive. Love will always be triumphant over hate.

"I know I will not be here forever, nor do I desire to be. I have seen progress like most cannot appreciate because they were not there to bear witness. I dedicated my life to the movement. By doing so, I never thought I'd still be here."

Death toll in SLeone flood disaster reaches 441

The death toll from a mudslide and flooding that struck Sierra Leone's capital Freetown has reached 441, the government said on Saturday.

"Four hundred and forty-one corpses (were) buried as at yesterday," the deputy minister of information and communication, Cornelius Deveaux, told AFP, adding that the number of missing was "still being calculated."

A tally of deaths, issued on Friday by the Red Cross, stood at more than 400, with around 600 others listed as missing.

At Connaught Hospital, morgue worker Mohamed Sinneh Kamara gave a slightly higher toll than the minister's.

"We buried 50 more bodies on Friday. We have so far buried 450 corpses," he told AFP. "Most of the bodies were found decomposed and families were not allowed to identify (them)."

He added: "We're receiving calls from disaster-hit communities every three to four hours about a corpse found in a drainage or under a collapsed building."

Three more bodies were found in a search for survivors in the Regent district, where the side of a hill collapsed, the emergency services said.

The disaster struck on Monday after Freetown, home to 1.2 million people and the capital of one of the world's poorest countries, had been pounded for three days by torrential rain.

According to the charity Save the Children, the disaster killed 122 children and left 123 orphaned.

The Red Cross has issued an emergency funding appeal. Britain, the former colonial power in Sierra Leone, has pledged £5 million ($6.45 million, 5.45 million euros), while China has pledged $1 million (850,000 euros) and Togo $500,000.

Water-borne diseases such as cholera and malaria are a major fear.

Flooding is an annual menace in Sierra Leone, where ramshackle homes are regularly swept away by seasonal rains. In 2015, floods killed 10 people and left thousands homeless.
