Rebel forces in Syria claim that the Syrian army, loyal to President Bashar Assad, has used phosphorus bombs against them, even though such weapons are illegal according to international law, Ynet reported Thursday, December 27. Rebel forces have uploaded videos showing bombs being fired as well as the damage caused by the alleged phosphorus shells, though no injuries or casualties were reported. The claims join earlier reports by rebels of a fatality caused by an unknown chemical. Furthermore, just this month Human Rights Watch claimed that Assad’s army has used incendiary bombs. Such bombs contain highly flammable chemicals such as napalm, thermite or phosphorus, which can cause fires, lead to chemical burns or damage airways. In the meantime, conventional warfare continued in full swing. Opposition activists reported 49 deaths throughout the country Thursday.
