Dozens of Islamic State fighters were killed over the weekend by the Afghan air force making a string of gains in the same area where U.S. forces helped take out the region’s ISIS boss, the government announced on Monday.

At least 34 ISIS fighters were killed in airstrikes in eastern Nangarhar province, Afghan officials said. That’s the same area where the terror group’s top local commander was killed by Afghan and U.S. military forces in April.

Confirmation of the death of Abdul Hasseeb Logari, the ISIS chief in Nangarhar, came on Sunday night from the Pentagon. Logari was among several senior leaders of the ISIS affiliate in Afghanistan and was killed in an April 27 raid jointly conducted by Afghan Special Security Forces and the U.S.

Logari was responsible for ordering a March attack on a military hospital in Kabul, according to the office of Afghan President Ashraf Ghani, which also confirmed the terror leader’s death. Around 50 people were killed and many others injured in that attack.
