The world's governments are urged to rename the roads where the Saudi Arabian embassies find the murdered journalist at the site of "Khashoggi Street".
In London, Amnesty International's activists held a false Khashoggi Street signal at 1.14 am for a month outside the Saudi Embassy, as Jamal Khashoggi entered Istanbul at the Saudi Consulate.
A dissident journalist who is a Washington Post and a strict critic of the Saudi regime, have not yet seen it and are presumed to have been murdered inside the building.
The movement began in America, where Khashoggi's friends and admirers launched Washington officials to rename New Hampshire Avenue, where the Saudi Embassy is called "Jamal Khashoggi Way."
The assault of the presumed murderer of the reporter overseas has spread. Amnesty International hopes that Mayfair, outside of the Saudi embassy, will instigate governments around the world to follow suit.
Kate Allen, director of Amnesty International UK, said: "The whole world was shocked by this grotesque murder, and it is vital that we do not let despair run out without justice.
"We have to see the killing of Jamal Khashoggi's murderers – not just those who actually executed the murder, but those who ordered it and knew it was going to happen.
The sixty-year ban on London's memorial in London, a leader of an influential American Islamic think tank, and Mr Khashoggi, Nihad Awad, long-a friend urged mourners to initiate petitions in every city where Riyad's diplomatic mission.
"We asked for a roundabout in front of the Saudi Embassy in Washington to name it after Jamal Khashoggi," Mr Awad announced.
"I want you to launch a petition that every street and every city where there is a Saudi embassy or a Saudi mission demands that it will be renamed.
"Imagine sending your letter to Khashoggi Way, how did their contacts contain such a title?"
Up to now, more than 1,800 people have been named for the Washington DC petition. The duo behind the Washington think tank on the opposite side of the two politicians, but outraged at Khashoggi's killing.
When the petition is signed for two thousand, the couple plans to find a city council or mayor, Muriel Bowser, to ask for a change of name.
The petition states that the renaming "would remind the Saudi officials daily that this behavior is totally unacceptable and that the unwavering support of Washington is to express freedom of the press".
Amnesty International also said that they are demanding an independent UN investigation into the disappearance of Khashoggi and warned the de facto leader of the country, Mohammed bin Salman, Crown Prince, to curb the dissidents and activists of oppressive empires.
"Since September 2017, when authorities launched a wave of detention for activists, writers and religious priests, Amnesty was able to monitor 20 arrests," he said.
"Some of the detainees are now in pursuit of the country's notorious terrorist court."
Prince Mohammed, who became a prince in June last year, introduced many social reforms, including eventually allowing the Saudi women to be led, but followed aggressively the authoritarian regimes and internal enemies of Saudi Arabia at the Saudi headquarters.
He also heightened Saudi Arabia's involvement in the bloody war against allies of rebels against Yemen is the largest rival of the kingdom in the Middle East, Iran.
But despite the fact that the country is one of the most important allies of the West, the increasing number of voices expresses discontent in its leadership.
Even Donald Trump, who has resisted, calls for sanctions in Saudi Arabia after the murder, as the nation is one of the largest US arms vendors, said Prince Mohammed had to know about the plan for killing journalists.
More than 100 new writers, journalists, artists and activists have echoed Amnesty International's call for the United Nations to investigate the disappearance of Khashoggi. Of those who have received open letters coordinated by PEN America, JK Rowling, Meryl Streep, Patrick Stewart, Bob Woodward Watergate journalist and Margaret Atwood novelist.
If the London or Washington authorities agree to rename the street address of the Saudi embassies, it would not be the first time that such a stunt drifted.
Famous for its name, Iran changed the name of the road in Tehran outside of the British Embassy to Bobby Sands Street after the IRA head of a 66-day hunger strike in 1981.
More recently, the Washington council marks street signs outside the Russian embassy, which marks the Boris Nemtsov Plaza, in honor of the assassination assassinated in Moscow.
