AKIPRESS.COM - At least 27 people were killed and dozens injured when a Syrian army fighter jet crashed into a busy marketplace in the rebel-held northwestern town of Ariha, RTE News reports.

Most of the dead were civilians on the ground in the Idlib provincial town that fell to a coalition of Islamist insurgents in May.

Scores were also injured, according to witnesses. There was no immediate reaction from the Syrian army.

The military plane had dropped a bomb in the heart of the city center main commercial street where shopkeepers open in the early morning before crashing in the middle of the marketplace, two witnesses said.

"The plane had dropped a bomb on the main bazaar street at low altitude only seconds before it crashed," said Ghazal Abdullah, a resident who was close to the incident.

The Observatory said the jet was not shot down.

Fighting has intensified of late in rural Idlib province between government forces and an insurgent grouping called Jaishal Fateh, or Army of Conquest, which includes Syria's al-Qaeda offshoot Nusra Front.

Ariha's fall had left the insurgents in control of most of Idlib province, which borders Turkey and neighbors Latakia, the heartland of President Bashar al-Assad's Alawite sect, on the Mediterranean coast.
