KABUL, Afghanistan – Heavily armed Taliban gunmen stormed a lakeside hotel near Kabul, sending terrified guests jumping from windows or into a lake to try to escape the onslaught. Eighteen people were killed in the 12-hour rampage, their bullet-riddled bodies strewn on carpets, on the lawn and a blood-smeared patio.

The attack, which ended at midday Friday, was a gruesome reminder of the Taliban’s determination to scare the Afghan people and undermine efforts to stabilize the nation as U.S.-led forces prepare to withdraw by the end of 2014.

The insurgents arrived shortly before midnight at the Spozhmai hotel, situated in a wooded area on the banks of the turquoise-colored Lake Qargha, where Afghan families often go to relax and forget about the war.
