An explosion tore through a mosque near the northern Afghan city of Kunduz on Friday killing at least 33 people and wounding dozens of others.

“The blast occurred at a mosque in Imam Sahib district of Kunduz killing 33 civilians including children,” Information Minister Zabihullah Mujahid said on Twitter, adding another 43 people were wounded.

“We condemn this crime … and express our deepest condolences to the victims,” said Mujahid.

Friday’s bombing is the latest in a series of deadly attacks across Afghanistan. Mujahid called the perpetrators of the Kunduz attack “seditionists and evil elements”.

Images posted to social media – which could not be immediately verified – showed holes blown through the walls of the mosque, popular with Sufis in the Imam Sahib district, north of Kunduz city.

It was not clear who was behind the attack, which came after several blasts claimed by the armed group ISIL (ISIS) rocked Afghanistan, including one in Kunduz and another on a Shia mosque in Mazar-i-Sharif, on Thursday.

Armed groups such as ISIL bear a deep hatred for Sufis who they view as heretics.

“The sight at the mosque was horrifying. All those who were worshipping inside the mosque were either injured or killed,” Mohammad Esah, a shopkeeper who helped ferry victims to the district hospital, told AFP news agency.

“I saw 20 to 30 bodies,” another local resident said.

Relatives of victims were arriving at hospital to look for their loved ones.

“My son is martyred,” screamed a man while a woman accompanied by her four children searched for her husband.

Kunduz police said they were investigating the type of explosion.

Taliban security challenge
Friday’s blast was one of the biggest attacks since the Taliban seized power in August last year.

In October, a suicide attack at a Shia mosque, also in Kunduz, killed at least 55 people and wounded scores – an attack also claimed by ISIL.

ISIL is a Sunni group like the Taliban but the two are bitter rivals. The biggest ideological difference between the two is that the Taliban sought only an Afghanistan free of foreign forces, whereas ISIL wants an Islamic caliphate.

The deadliest of three bombings on Thursday exploded inside a Shia mosque in northern Mazar-i-Sharif with at least 12 people killed and as many as 40 wounded.

Earlier Thursday, a roadside bomb exploded near a boys school in the Afghan capital of Kabul, injuring two children in the city’s predominately Shia neighbourhood of Dasht-e-Barchi. A third bomb in Kunduz wounded 11 mechanics working for the country’s Taliban rulers.

Since sweeping to power last August, the Taliban has been battling an ISIL affiliate known as Islamic State in Khorasan Province, which is proving to be an intractable security challenge.
