European Union foreign ministers on Monday debated ways to maintain support for the Afghan government after a brutal weekend attack on a girl’s school underscored deep concern that violence will spread as US-led troops leave the country.

“After the terrible attacks of recent days, it is all the more important for the EU to make very clear that Afghanistan and the Afghan government can continue to count on Europe’s support,” German Foreign Minister Heiko Maas told reporters in Brussels.

“We will continue to make available sufficient funding for civilian reconstruction, and we will do everything we can so that the ongoing peace negotiations reach a conclusion,” Maas said.

Violence remains high in the country after US and coalition forces announced their withdrawal from Afghanistan.

The Taliban announced a three-day ceasefire on Sunday that will be observed during Eid days later this week, but on Monday a bus carrying civilians was struck by a roadside bomb blast in which at least 11 civilians were killed.

President Ashraf Ghani ordered Afghan forces to observe the Eid ceasefire, but asked the Taliban to agree on a “real and permanent” ceasefire and to return to the negotiations table.
