>> The US military dropping the biggest non-nuclear bomb in Afghanistan Thursday. As seen here in a test, the explosive, nicknamed the mother of all bombs, was dropped at 7 PM local time from an NC-130 aircraft in the Achin District of Nangarhar province, close to the border with Pakistan.
>> The United States military used a GBU-43 weapon in Afghanistan. The GBU-43 is a large, powerful, and accurately-delivered weapon. We targeted a system of tunnels and caves that ISIS fighters used to move around freely, making it easier for them to target US military advisors and Afghan forces in the area.
>> This bomb was allegedly developed during the Iraq War, but was used for the very first time on Thursday. Reuters correspondent, Idrees Ali.>> What makes this different is the fact that the type of bomb that was used is much heavier and much stronger than anything that's been used in Afghanistan or, really, in the world by United States before.
So it's the type of munition rather than the type of strike that's important. So the question that's being asked is, is this part of a broader military and more powerful military doctrine? And this strike, while it does stand out, people, I think, are saying that it necessarily doesn't mean that he's gonna take a harsher or stronger line in Afghanistan.
That's not clear yet.>> Elsewhere in the fight against Islamic State, the Pentagon revealing that a US-led airstrike in Syria mistakenly killed 18 members of a local militia group backed by Washington. The strike was the third time in a month that American-led forces may have inadvertently killed allies or civilians.
Including a strike on a building in Mosul, Iraq, that may have killed as many as 200 civilians.
