At least 52 people were killed and dozens wounded on Tuesday, January 15 in two explosions that rocked the university in Aleppo, Syria's biggest city, the Syrian Observatory for Human Rights said, according to Reuters.

Two explosions hit the university during the day while students were sitting exams. The cause of the explosions was not clear but the government and opposition activists blamed each other.

The Observatory said in a statement that its death toll was based on reports from doctors and students.
