In what the Prime Minister of New Zealand described the darkest day in the history of the country, and the worst terrorist attack in the country so far 49 Muslims belonging to different nationalities and ethnic groups praying together in mosques were massacred by white supremacist terrorists. The Queen of Commonwealth, Pope and many other world leaders have sent notes of sympathy to the government.

This is what we know so far:

A white supremacist entered a mosque on Deans Avenue, Christchurch where Muslims had gathered to pray. He was carrying a semi-automatic weapon. He opened fire indiscriminately as there were so many targets busy praying. He was streaming the attack live. IslamiCity writer saw the video and due to its nature, and in honor of the victims it would not be published.

Another white supremacist entered a mosque in Linwood.

49 Muslims are dead as of now. 41 at the Central mosque, 7 at Linwood mosque and one in Christchurch hospital. 48 people have been admitted to the hospital with gunshot wounds as of now. Others have been sent to medical centers. The terrorist has been charged and would appear in the Christchurch District Court on Saturday morning.

He was arrested in a city street in a car with explosives and more guns inside. The terrorist described himself as 28-year old Australian Brenton Tarrant. The terrorists were not on the watch list of police either in Australia or New Zealand.

Tarrant had issued a manifesto glorifying white supremacy and had asked the people of the US and Europe to oust immigrants and build a pure white society. Police arrested four people initially, three including Tarrant are in custody. The fourth person was not related to the events, police said.

There was a chaotic scene at Christchurch hospital that has only 12 operating theaters in use for people requiring multiple surgeries. Families of the victims and others came to hospitals and at the mosques looking for their loved ones.

Families have shown up at the hospital and at the Deans Ave cordon seeking news of family members. The police have set up a missing people's register. Witnesses have given detailed accounts of the horror of their co-coreligionists being killed. Victim support has launched an official fund to support the families of the victims.

Leaders from around the world have condemned this terrorist act. Pope Francis has denounced the "senseless acts of violence" in the Christchurch mosque shootings and said he was praying for the Muslim community and all New Zealanders.

In a telegram of condolences Friday, Francis offered his solidarity and prayers to the injured and those who are mourning lost loved ones and noted that it was a particularly difficult time for security and emergency personnel.

He said he was "deeply saddened to learn of the injury and loss of life caused by the senseless acts of violence at two mosques in Christchurch, and he assures all New Zealanders, and in particular the Muslim community, of his heartfelt solidarity in the wake of these attacks."

The message sent by the Vatican secretary of state ended by saying, "Commending those who have died to the loving mercy of Almighty God, Pope Francis invokes the divine blessings of comfort and strength upon the nation."

Meanwhile, Muslim civil rights and advocacy organizations in the USA have issued press releases mourning the deaths of more than 40 worshipers gunned down in terror attacks on two mosques in Christchurch, New Zealand, during prayers on Friday, and condemned the apparent anti-Muslim and anti-immigrant hate that motivated the attacks and urged mosques in the United States and worldwide to step up security measures.

The white supremacist author of the manifesto called himself a supporter of President Donald Trump, who he sees "as a symbol of renewed white identity and common purpose."

There has been an unprecedented spike in bigotry targeting American Muslims, immigrants, and members of other minority groups since the election of Donald Trump as president and has repeatedly expressed concern about Islamophobic, white supremacist and racist Trump administration policies and appointments.

Mosques and other Islamic institutions should take measures to protect the safety of people visiting places of worship. This is applicable to all institutions, regardless of the organizational mission. (See: What to do during an active shooting)

The white supremacist terrorist issued a 73 page manifesto justifying his massacre. In this he praised President Donald Trump. The manifesto published in a question and answer form asked the following:

"Were/are you a supporter of Donald Trump?  The response: Sure, as a symbol of renewed white identify and common purpose? As a policymaker and leader? Dear God no."

The manifesto has been removed from the website. The terrorist in 73 pages talked about American conservative commentator Candace Owens and says, "Yes the person that had influenced me above all is Candace Owens. Each time she spoke I was stunned by her insights and her own views helped me further and further into the belief of violence over weakness. Thus, I will have to disavow some of her beliefs, the extreme actions she calls for are too much even for my tastes."

Owens is the director of communications at the conservative advocacy group Turning Point USA, and known for her pro-Trump stance and her criticism of Black Lives Matter and of the Democratic Party.
