BEIRUT- Syrian regime helicopters has dropped barrel bombs on opposition-held districts in the northern city of Aleppo, killing at least 30 people including several children, an NGO said.
The Syrian Observatory for Human Rights said a number of people were injured, some of then seriously, in the attacks on the Sukkari and Ashrafiyeh neighbourhoods.
The group distributed gruesome images from the scene of the attacks on Sukkari, where 24 people were killed, showing residents holding body parts of victims from the raid.
Observatory director Rami Abdel Rahman said a first attack created chaos, with residents and medics rushing to the scene to help.

Several minutes after the first attack, a second bomb was dropped on the same site, with those there trying to flee but many failing to do so in time.
Another six people died in a separate barrel bomb attack in a rebel-held area in Ashrafiyeh neighbourhood, in the north of the city.
Syria's regime has waged a fierce aerial offensive against rebel-held parts of Aleppo since last December.
The Observatory said in May that the campaign had killed nearly 2,000 people -- more than a quarter of them children -- since the beginning of 2014.
Rights groups have decried the regime's use of barrel bombs as unlawful because they lack an aiming mechanism, causing indiscriminate casualties.
Tens of thousands of people have fled Aleppo's opposition districts because of the aerial campaign.
Elsewhere, the Observatory said 11 people, including eight children, were killed on Sunday night by rebel shelling of a government-held area in western Idlib province.
More than 162,000 people have been killed in Syria's conflict, which began with peaceful protests against President Bashar al-Assad's regime in March 2011 before spiraling into a bloody war after a massive government crackdown on dissent.
