Top news: The Turkish military shelled targets inside Syria on Wednesday after a Syrian mortar round killed five Turkish civilians. The attacks were the most serious indication that Syria's civil war could spill into neighboring countries and the worst cross-border escalation of the months-long crisis.
NATO, of which Turkey is a member, convened an emergency meeting after the exchange and issued a statement strongly condemning Syria's "flagrant violations of international law" and reaffirming the alliance's intention to stand behind Turkey.
Elsewhere in Syria, violence escalated as suicide bombers struck targets in Aleppo, killing dozens of people. The blasts, which struck government-owned hotels and a public square, were claimed by Jabhet al-Nusra, an insurgent group affiliated with Al Qaeda.
