At least 14 were killed and 26 wounded after a car bomb exploded near the border of Turkey and Syria early Tuesday, according to the Ministry of Justice. The incident took place at the Cilvegozu border post—a main crossing for Syrian refugees carrying goods back and forth between the two countries. A spokesperson for the Turkish government said that the “powerful explosion” was carried out by Syrian forces. “The information that we have for now is that a minibus with Syrian number plates coming from the other side exploded,” he said. Violence between the two nations continued to escalate Tuesday, as Syrian rebels captured a crucial military base, al-Jarrah airfield.
