AKCAKALE, Turkey (AP) — Turkey's Parliament authorized military operations against Syria on Thursday and its military fired on targets there for a second day after deadly shelling from Syria killed five civilians in a Turkish border town.

For its part, Syria admitted it was responsible for the shelling that killed five people in Turkey and formally apologized for the deaths, a top Turkish official said.

Deputy Prime Minister Besir Atalay said Syria has reassured the U.N. that "such an incident will not occur again."
