7 killed in explosion in Kabul

At least seven people were killed and another 20 injured in an explosion in Afghanistan 's capital Kabul on Tuesday, an official said.

The explosion, latest in a string of blasts across the country in recent months, targeted a passenger bus in Dasht-e Barchi area of Kabul, city's security department's spokesman, Khalid Zadran said in a statement.

The security forces have cordoned off the area, he said without providing further details.

The Taliban government has been struggling to contain a low-intensity wave of terrorist attacks, mostly claimed by ISIS or Daesh, since the militia re-captured Kabul two years ago.

Last month, at least seven people were killed and 17 others injured in a suicide blast targeting a mosque in northern Baghlan province.
