KABUL, Afghanistan -- A suicide bomber struck a private education center in a Shiite neighborhood of Kabul on Wednesday where high school graduates were preparing for university entrance exams, killing 48 young men and women and leaving behind a scene of devastation and tragedy.
The bombing, blamed on the Islamic State group, was the latest assault on Afghanistan's Shiite community, which has increasingly been targeted by Sunni extremists who consider Shiites to be heretics.
It also showed how militants are still able to stage large-scale attacks, even in the heart of Kabul, and underscored the struggles of the Afghan forces to provide security and stability on their own.
The attack comes during a particularly bloody week in Afghanistan that has seen Taliban attacks kill scores of Afghan troops and civilians.

It was not immediately clear how the bomber sneaked into the building, used by the Shiite community as an education center, in the Dasht-i Barcha area of Kabul.
The spokesman for the public health ministry, Wahid Majroh, said 67 people were wounded in the bombing and that the death toll -- which steadily rose in the immediate aftermath -- could rise further. He did not say if all the victims were students and whether any of their teachers were among the casualties.
The explosion initially set off gunfire from Afghan guards in the area, leading to assumptions that there were more attackers involved, but officials later said all indications were that there was only one bomber.
No group immediately claimed responsibility for the attack but Jawad Ghawari, a member of the city's Shiite clerical council, blamed the Islamic State, which has carried out similar attacks on Shiites in the past, hitting mosques, schools and cultural centers. In the past two years, there were at least 13 attacks on the Shiite community in Kabul alone, he said.
Afghan President Ashraf Ghani condemned the "terrorist" attack that "martyred and wounded the innocent" -- students attending class -- and ordered an investigation into the attack.
"By targeting educational and cultural centers, terrorists have clearly shown they are against all those Islamic principles [that strive] for both men and women to learn and study," Ghani said in a statement.
The head of the U.N. children's agency denounced the attack, saying it's "deplorable" that children continue to be hardest hit in the growing violence across Afghanistan.
"Children are not, and must never be the target of violence," said UNICEF's executive director Henrietta Fore.
Meanwhile, a Taliban assault on two adjacent checkpoints in northern Afghanistan late Tuesday killed at least 30 soldiers and policemen.
The attack took place in Baghlan province's Baghlan-I Markazi district, said Mohammad Safdar Mohseni, head of the provincial council.
Dilawar Aymaq, a parliamentarian from Baghlan, said the attack targeted a military checkpoint and another manned by the so-called local police, militias recruited and paid by the Interior Ministry.
At least nine security forces were still missing and four others were wounded in the attack, said Abdul Hai Nemati, the governor of Baghlan. He said reinforcements have been dispatched to help recapture the checkpoints.
Taliban spokesman Zabihullah Mujahid claimed responsibility for the assault.
Elsewhere in Afghanistan, the Taliban attacked a police checkpoint in the southern Zabul province early Wednesday, killing four policemen, according to the provincial police chief, Mustafa Mayar.
The Taliban have seized several districts across the country in recent years and carry out near-daily attacks targeting Afghan security forces. The assault on Ghazni was widely seen as a show of force ahead of possible peace talks with the U.S., which has been at war in Afghanistan for nearly 17 years.
Also Wednesday, six children were killed when they tinkered with an unexploded rocket shell, causing it to blow up, said Sarhadi Zwak, spokesman for the governor of the eastern Laghman province. The victims were girls, aged 10-12, who were gathering firewood, he said, blaming the Taliban.
Afghanistan is littered with unexploded ordnance left by decades of war. It is also plagued by roadside bombs planted by insurgents, which are usually intended for government officials or security forces, but often kill and maim civilians.
