Border guards shot dead five Syrian citizens including a one-year-old baby girl as they tried to cross Turkey's tightly controlled border from Hatia in northwest Idlib province, a monitoring group said on Wednesday.
Two other men were wounded by Turkish border guards in the incident, the UK-based Syrian Observatory for Human Rights reported.
It relies for its information on a network of activists and doctors inside Syria.
A violent explosion was also heard on the road between the area of Bensia and Harem in Idlib's northern countryside, said the watchdog.
As the civil war between pro-government forces and rebels reaches its endgame, Idlib has become a dumping ground for civilians and fighters bussed northward from rebel-held areas across Syria that have submitted to government control in recent months.
Turkish border guards have shot and beaten civilians caught crossing illegally, Human rights groups including Amnesty International and Human Rights Watch have reported.
