On Tuesday, the top U.S. General Kenneth McKenzie warned that ISIS will likely ramp up its attacks this summer as the Taliban struggles in its effort to shut down the terror group in Afghanistan.

Fox News reports:

“The Taliban is attempting to maintain pressure on ISIS. They’re finding it difficult fo do so,” McKenzie said in response to a question from Sen. Angus King, I-Maine.

McKenzie noted that in recent months ISIS has carried out “some high-profile attacks” in Afghanistan, including in the capital city of Kabul. This, he said, was even before the time of year when such attacks are typically on the rise.

“We’re coming out of the winter; traditionally this would now begin the fighting season,” McKenzie said. “It is my expectation that ISIS attacks will ramp up in Afghanistan as we go into the summer.”

McKenzie was not confident at all that the Taliban would stop al Qaeda from being active, saying he believes that “they’re much less firm on the al Qaeda issue as far as opposing them and being able to limit them.”

The Taliban quickly retook control of Afghanistan as American forces withdrew. During the U.S. withdrawal, ISIS-K carried out a suicide bombing at an airport in Kabul which killed 13 U.S. service members.
