Alwaght- Death toll from US-led coalition's Monday airstrike on an eastern Syrian town has rose to over 30 people, including women and children, Reuters reported.
Coalition spokesman US Air Force Colonel John Dorrian confirmed that they had conducted strikes in the vicinity of the town of Bukamal, but said he could not "confirm the veracity of allegations of civilian casualties".
Airstrikes by the US-led coalition have killed dozens of civilians over the past several weeks.
In a similar incident US fighter jets strucj on 17 March a crowded mosque, Omar Ibn al-Khattab, in Aleppo's Jeeneh district that killed 46 civilians.
While American officials claimed they have targeted an al-Qaida gathering, Human Rights Watch's published a 16-page report saying that it found no evidence to support the allegation that members of al-Qaida or any other armed group were meeting in the mosque. It said a religious lecture was being held at the time of the attack and prayers were about to begin.
"The US seems to have gotten several things fundamentally wrong in this attack, and dozens of civilians paid the price," said Ole Solvang, deputy emergencies director at Human Rights Watch.
"The US authorities need to figure out what went wrong, start doing their homework before they launch attacks, and make sure it doesn't happen again," Solvang said.
The HRW report is based on interviews with more than a dozen people with firsthand knowledge of the strike. The rights body also worked with organizations to analyze the imagery of the attack and reconstruct the assault.
"Any attempt to verify through people with local knowledge what kind of building this was would likely have established that the building was a mosque."
The rights group also stated that it had found no evidence that militants were inside the mosque.
Elsewhere in the report, the HRW said even if they had been "striking a mosque just before prayer and then attack people attempting to flee, without knowing whether they were civilians or combatants, may well have been disproportionate or indiscriminate."
"Indiscriminate or disproportionate attacks violate the laws of war, as does failing to take all feasible precautions to minimize civilian deaths."
The HRW said it had submitted its findings to the US Central Command.
