At least nine pro-regime fighters died in an overnight strike in northern Syria blamed on Israel, a monitor said Monday. 
Syrian state media had accused Israel of bombing a military position in Aleppo province late Sunday, in what would be a rare Israeli attack so far north in the war-ravaged country. 
The Syrian Observatory for Human Rights, a Britain-based monitor, said Monday that those killed included at least six Syrians and that Iranian fighters were also stationed at the base.
