At least 36 Islamic State of Iraq and Syria (ISIS) militants are reported dead after the second major US military strike in a week's time. 

The U.S. military dropped what it called the Mother of All Bombs on ISIS militants in Afghanistan.

Afghan officials say this Massive Ordinance Air Blast bomb killed 36 ISIS militants and that no civilians were harmed.

This is the second time in a week that the U.S. launched a major attack. Just last week there was a surprise strike on a Syrian airfield

The Ministry of Defense said in a statement that several ISIS caves and ammunition caches were destroyed by the giant bomb, which terrified villagers on both sides of the Afghanistan-Pakistan border with its "earsplitting blast."

And the move is getting a lot of reaction from Congress. Some are insisting that President Donald Trump consult Congress before he acts again.

Trump called this "another very, very successful mission," but he would not say if he directly authorized the bombing.

However, the president is getting support from Florida U.S. Sen. Marco Rubio.

And Rubio is not the only Republican praising the bombing:

However, Democrats are calling for a plan to be laid out and want Congress to have more input in military decisions.
 

The hashtag stands for Authorization for Use of Military Force, which gives the president authorization to take action in order to prevent future terrorist attacks on the U.S. It was put in place after 9/11.

The U.S. estimates 600 to 800 IS fighters are present in Afghanistan, mostly in Nangarhar. The U.S. has concentrated heavily on combatting them while also supporting Afghan forces battling the Taliban. President Donald Trump called Thursday's operation a "very, very successful mission."

The bomb, known officially as a GBU-43B, or massive ordnance air blast weapon, unleashes 11 tons of explosives.

Inamullah Meyakhil, spokesman for the central hospital in eastern Nangarhar province, said the facility had received no dead or wounded from the attack.

District Gov. Ismail Shinwari said there is no civilian property near the airstrike location.

There was no immediate comment from the ISIS group or other militants regarding the U.S. bomb attack.
