Washington (CNN) The US military ramped up the number of air and artillery strikes it conducted in Afghanistan during the month of September following the collapse of the peace talks with the Taliban after President Donald Trump canceled a Camp David summit with the insurgent group on September 7.

US troops carried out 1,113 air and artillery strikes during the month of September, according to statistics released by the US military compared to 810 such strikes in August and just 465 strikes in September of 2018.

"We had peace talks scheduled a few days ago. I called them off when I learned that they had killed a great American soldier from Puerto Rico and 11 other innocent people. They thought they would use this attack to show strength. But actually, what they showed is unrelenting weakness. The last four days, we have hit our enemy harder than they have ever been hit before, and that will continue," Trump vowed at a Pentagon ceremony marking the anniversary of the September 11th attacks.

In that four-day period referenced by Trump the US conducted some 153 strikes between September 8 and September 11, according to the data.

"U.S. forces do not purport that strikes are decisive; however, we may occasionally talk about this information to provide context." US Forces Afghanistan said in a statement accompanying the statistics.
