ANKARA, Turkey (AP) — Turkey's deputy prime minister says that only Syria's government is in possession of the type of chemical weapons that Syria's opposition says were used in an attack in the eastern suburbs of Damascus that killed at least 100 people.

Bekir Bozdag urged the international community on Thursday to act against "this crime against humanity," and put a stop to Syrian President Bashar Assad's violence.

Syria's government has denied allegations it used chemical weapons in artillery barrages, which the country's opposition groups say left at least 100 people dead.

The U.S., Britain and France have demanded that a team of experts already in the country be granted access to investigate the site.

Bozdag said: "How many more people must die before you say (to Syria) 'This is enough.'"
