Pentagon: US dropped largest non-nuclear bomb in Afghanistan

Test footage shows just how big a blast the huge missile - officially called GBU-43/B Massive Ordnance Air Blast Bomb - produces. US forces took "all precautions necessary to prevent civilian casualties and collateral damage", he said. The munition was developed during the Iraq war and is an air blast-type warhead that explodes before hitting the ground in order to project a massive blast to all sides.

"This is the right munition to reduce these obstacles and maintain the momentum of our offensive against ISIS-K", he added, noting that US forces will proceed with such operations "until ISIS-K is destroyed in Afghanistan". The Islamic State has an estimated 600 to 800 fighters in Afghanistan, according to Pentagon spokesman Adam Stump. That the Pentagon would deploy the weapon indicates that military leaders see ISIS as an persistent threat in the area.

After attacking ISIS militants in Afghanistan with a massive weapon, dubbed the "mother of all bombs", Trump said he does not know whether it sends a message to the North but that it doesn't matter. The bomb will also "maintain the momentum of our offensive against IS", he said.

"The GBU-43B has been in the US arsenal for more than 14 years, deployed to bases in the Middle East where it could be loaded aboard an American aircraft but never used until now".

President Trump hailed the USA military after it dropped the "mother of all bombs", America's largest non-nuclear weapon, in Afghanistan on Thursday.

Markey wouldn't say what an acceptable number of civilian casualties is, but if there are casualties, he says it could backfire on the U.S. He's afraid ISIS could use it as a recruitment tool. Was it a response to the death of Staff Sergeant Mark De Alencar, a Special Forces soldier who was killed April 8 in the same province? "We are very proud of them and this was another very, very successful mission".

He declined to say whether he had been involved in the decision making.

"The Secretary General and I had a productive discussion about what more North Atlantic Treaty Organisation can do in the fight against terrorism", Trump said. This is the latest in the ongoing fight against ISIS.

"We have the greatest military in the world and they've done their job as usual".

In the run-up to the polls, Trump had promised to go after the Islamic State, saying he would "bomb the s*** out of them", a quote that became a popular T-shirt slogan but was the Thursday bombing about that?

The security situation remains precarious in Afghanistan, with a number of militant groups trying to claim territory more than 15 years after the USA invasion which toppled the Taliban government.

Testifying before the Senate Armed Services Committee in February, General John Nicholson warned of a stalemate in the country.

The attack comes as President Trump announced Wednesday that National Security Adviser H.M. McMaster would be heading to Afghanistan, to assess the current state of USA operations in the country. "So, we have given them total authorisation".
