Opposition forces fighting against Syrian President Bashar Assad accused the Damascus regime and Hezbollah of using chemical weapons on Wednesday in a town outside of the capital, Saudi-owned Al-Arabiya news network reported.
According to the report, activists from the Free Syrian Army (FSA) said chemical weapons were used in the town of Zamalka.
Last week in a call with reporters, the White House said evidence was clear that chemical weapons had been used against rebel forces in Syria.
United Nations Secretary-General Ban Ki-moon confirmed he had received the American findings, but that they are viewed with skepticism, and perhaps with bias as well.
