A large explosion in Kabul, Afghanistan today just after 4:30 a.m. local time had residents scrambling to social media for clues.

Early news reports suggest the explosion was part of an attack on a private company. Some sources named the target as No Lemon, which describes itself as “a valuable service provider for many UN organizations, government agencies, NGOs, embassies and commercial companies operating in developing and post-conflict countries. We are an internationally accredited company with operations in Africa, Afghanistan, Kosovo, and Iraq.”
