The strikes today came amid a stepped up air campaign in central and northern Syria the day after Islamic militants, including fighters from al-Qaida's local affiliate, seized an Alawite village.
Activists and pro-government media say scores of civilians were killed when the Sunni insurgents took over the central village of Zaara.
The Britain-based Syrian Observatory for Human Rights says the airstrikes in Idlib killed five people. Ahmad al-Ahmad, an activist from the nearby city of Hama, put the toll at six.
Both reported other airstrikes around Zaara.
