US military drops 'mother of all bombs on IS' in Afghanistan

The US military has dropped the biggest non-nuclear bomb ever used in combat on an Islamic State group tunnel complex in Afghanistan, the Pentagon says, BBC reports.

The GBU-43/B Massive Ordnance Air Blast Bomb (MOAB), known as "the mother of all bombs", was first tested in 2003, but had not been used before.

The Pentagon said it was dropped from a US aircraft in Nangarhar province.
