Time in Nigeria’s capital, Abuja, has fallen to 5.9 hours.
The city is among the worst hit by the deadliest mass shooting in modern Nigerian history, killing at least 50 people and wounding hundreds.
At least 1,000 others were injured.
President Muhammadu Buhari has been urging Nigerians to take up the torch of national mourning, calling for unity in mourning, unity in the face of terror.
But the country has been divided for months over the country’s response to the deadliest terror attack on Nigerian soil since 2009, when a suicide bomber detonated a suicide vest outside the home of a top Muslim cleric.
Buhari’s administration is under fire from some in the Muslim community for its response to Boko Haram, which has been blamed for the massacre in the capital.
The attack on the bus on Sunday was carried out by a group of men with links to Boko Shabu, a Boko Haram affiliate.
They drove up to the bus and fired several shots into the crowd before opening fire.
The attack was one of the deadliest attacks in the country since 2009 and triggered protests across Nigeria.
The government has blamed the attack on a small group of Boko Haram militants who are linked to an Islamist militia in the area.
Nigeria’s state-run broadcaster reported that the attackers opened fire on a group that was passing through a checkpoint near the bus stop.
It also said that two civilians were killed in the attack.

At least 50 dead and more than 150 injured in Nigerian mass shooting after Boko Haram attack.
A state of emergency was declared in the northeastern state of Kaduna and a curfew was in effect in the restive northern city of Kadoki, according to the Associated Press.
“Nigeryans have come together in their mourning and in the fight against terrorism,” Buhare said on Monday.
“We cannot allow these terror attacks to continue and we must continue to hold the state of fear and fearlessness.”
“Today, we stand in solidarity with the families of the victims of the terrorist attack in Nigeria and we call on all Nigerians, especially in the southern region, to remember the victims and their families.”
The country has seen a surge in terrorism in recent years, particularly targeting Christians and the military, according the International Crisis Group.
On Sunday, Boko Haram claimed responsibility for an attack in Kaduna that left more than 70 people dead.
On Monday, Nigerian officials said that Boko Haram has launched another attack targeting the military.
Prime Minister Muhammadu Gbir said that the country was facing an imminent threat of further attacks.
Mubarak Ntepama, an adviser to the president, told CNN’s Fareed Zakaria that the government is targeting those who are supporting terrorism.
He said the government was not going to let anyone in the military to support terrorism.
“No, we will not allow anyone to be part of this, we are not going back,” he said.
Abuja has been hit by a series of attacks in recent months.
The state has been rocked by protests and demonstrations over the death penalty, as well as an uptick in crime and drug trafficking.
In September, at least 30 people were killed and more 100 were wounded when a car packed with explosives exploded in a busy market in the city, sparking protests across the country.
The blast injured more than 200 people.
