KABUL (Reuters) -A bomb blast in the Afghan capital of Kabul wounded two people on Monday, the Taliban’s interior ministry said, just two days after a similar explosion that was claimed by the Islamic State militant group.

Both devices were of a magnetic type attached to vehicles that have become common in Afghanistan, generally causing fewer casualties and less damage than suicide attacks, but used in targeted killings that undermine confidence in security.

“I was busy with a customer when a boom shook the store,” said Ahmad Murtaza, a shopkeeper in Kabul’s western area of Kote Sangi.

“I saw people were taking victims from the blast site, I don’t know whether they were dead or injured.”

Interior ministry spokesman Qari Sayeed Khosty said the explosion was caused by a sticky bomb and hurt two people, but gave no details.

A similar magnetic bomb had destroyed a minibus in western Kabul on Saturday, killing and wounding several people.
