The Syrian opposition said on Friday armed groups fighting President Bashar al-Assad would respect a two-week truce beginning at midnight, but said the government and its allies must not launch attacks on the pretext of fighting terrorism.

"The High Negotiations Committee confirms the agreement of the Free Syrian Army factions and the armed opposition to a temporary truce from midnight Saturday," an HNC statement said.

The HNC said the government and its allies must not use the "proposed text to continue the hostile operations against the opposition factions under the excuse of fighting terrorism.”
