Syrian President Bashar Assad has dropped bombs containing toxic gases, killing six people and blinding others in Homs, Al Jazeera reported Monday.

Opposition forces released a video showing a victim struggling to breathe after the attack.

At least 181 people were killed on Sunday in attacks by loyalists to Assad, who may be have dealt himself a suicide blow by using chemical warfare, a move that the President Barack Obama has warned would justify US military intervention in the uprising that has erupted into civil war.

Russia, which is a major supplier of chemical weapons to Syria, claimed on Sunday that Assad had moved its chemical weapons stockpile to a” safe” place.

Al Jazeera said six people were paralyzed and four others were blinded by the toxic gas bombs, and 63 other suffered other injuries.

Syrian activists reported that Assad’s forces had committed a "horrible massacre" in the bombing of a bakery, killing more than 100 people.

They also said cluster bombs exploded in several towns as Assad desperately tried to fend off an increasingly armed opposition, beefed up by Islamic terrorists.
