Afghanistan’s president on Monday vowed to “eliminate” all safe havens of the Islamic State group as the country marked a subdued 100th Independence Day after a horrific wedding attack claimed by the local IS affiliate.

Axar.az reports citing Time that President Ashraf Ghani’s comments came as Afghanistan mourns at least 63 people, including children, killed in the Kabul bombing at a wedding hall late Saturday night. Close to 200 others were wounded.

A sharply worded Taliban statement questioned why the U.S. failed to identify the attackers in advance. Another Taliban statement marking the independence day said to “leave Afghanistan to the Afghans.” More than anything in its nearly year-long negotiations with the U.S., the Taliban want some 20,000 U.S. and allied forces to withdraw from the country.
