Syrian President Bashar al-Assad said that the European countries will "pay the price" if they send weapons to foreign-backed militants in the Arab country.
"If the Europeans deliver weapons, then Europe's backyard will become terrorist-like, and Europe will pay the price for it," Assad was quoted as saying by German daily Frankfurter Allgemeine Zeitung on Monday.
"Terrorists will become battle-skilled and return laden with extremist ideology," he added.
Assad also rejected US, British and French claims that Syrian forces had used chemical weapons against the foreign-backed terrorists fighting in the country.
“If Paris, London and Washington had even one piece of evidence for their claims, they would have presented it publicly,” he said.
Syria's deputy foreign minister, Faisal Muqdad, also criticized discussions by Western countries on arming Syria militants saying they are "incitement to murder and unacceptable on a human and moral level.”
"This is the principle of those who want continued killing in Syria," Muqdad added.
The comments came after US President Barack Obama ordered his administration last week to provide terrorists in Syria with weapons, claiming that the Syrian government had crossed Washington's "red line of what he alleged the use of chemical weapons against the militants.
