"The first incident was over a public park in the Bab al-Nairab area of the city where people had taken refugee from the shelling," said the spokesman, Abu Amir. "They were ordinary people who were defenceless against this type of attack." Videos on the internet show barrels that did not explode in Batbo, 20 miles west of Aleppo, as well as three locations in Idlib province and in Homs.
