Afghanistan's president, Ashraf Ghani, has described a massive bomb attack in the capital Kabul as a crime against humanity.
The blast, near Kabul's busy Zanbaq Square and the German and United States embassies, has killed at least 90 people and injured hundreds of others.
Afghanistan's intelligence service says evidence suggests the Haqqani network, an armed group affiliated with the Taliban, carried out the attack, with Pakistan's help.
But the Taliban has denied involvement, and Pakistan denies supporting cross-border militants.
Local hospitals have been flooded with casualties.
This man, recovering from the attack, described the moment of the blast.
(Dari, then translated:) "I was working in the office when a powerful blast happened. I collapsed under the desk and received injuries from shattered windows."
A tanker, laden with explosives, blew up during the morning rush hour in a busy part of the city that houses many foreign embassies and government departments.
The Afghan president says he shares his country's pain.
(Pashto, then translated:) "I express my deepest condolences to the families of victims following today's terrorist attack in Kabul city, which martyred and wounded a number of our countrymen and damaged public installations. It was a brutal act, which has caused our countrymen grief in this holy month of Ramadan." (Pashto ...)
The neighbourhood is supposed to be Kabul's safest, with around-the-clock security and dozens of three-metre-high blast walls.
The blast struck near the fortified entrance to the German embassy compound, killing one of the embassy's guards.
It happened on the day Germany was planning to deport a group of failed asylum seekers back home to Afghanistan.
Germany has now announced a temporary suspension of the deportations, saying they will resume once the embassy is operating again.
German chancellor Angela Merkel had this message for those behind the attack:
(German, then translated:) "All of us who believe in the rights, in the freedom and in the dignity of mankind in Europe, in America, in Africa, and, of course, in Afghanistan, too, will wage war against terrorists, and we will win." (German ...)
The Secretary of the Department of Foreign Affairs and Trade for Australia, Frances Adamson, says staff at the Australian embassy were not hurt.
Australia does not make public the location of its embassy in Kabul for security reasons, but Ms Adamson says it was 900 metres from the explosion.
The blast comes just days after Australia confirmed it would add 30 soldiers to its training and advisory forces in Afghanistan.
Prime Minister Malcolm Turnbull has condemned the attack in parliament and says Australia will continue supporting the Afghan government.
"Almost all of those affected were civilians, many of whom (were) women and children. This shocking attack comes in the holy month of Ramadan. I know that all Australians condemn the actions of those responsible. And I've written today to President Ghani to express our deepest sympathies and to restate Australia's resolve to assist and support Afghanistan in its fight against Islamist terrorism."
