AMMAN - The head of a new alliance of Syrian Islamist factions, including a former affiliate of al Qaeda, has promised to escalate attacks against the Syrian army and its Iranian-backed allies with the goal of toppling President Bashar al-Assad.
Hashem al-Sheikh, leader of Hayat Tahrir al-Sham, which was formed last month, also said in his first video speech that the new grouping sought to "liberate" all of Syria's territory.
"We assure our people that we will begin our project by reactivating our military action against the criminal regime and we will raid his barracks and positions and wage a new battle of liberation," he said.
Hayat Tahrir al-Sham, or Body for the Liberation of the Levant, was created from a merger of Jabhat Fateh al Sham - formerly al Qaeda's Nusra Front - and several other groups.
The jihadist alliance has enlisted thousands of fighters who have defected in recent weeks from more moderate Free Syrian Army rebel groups, angered by their leaders' readiness to engage in a peace process with Assad's government.
Days before the alliance came into being, heavy fighting erupted in northwestern Syria between Fateh al Sham and more moderate rebel groups, threatening to further weaken the opposition to Assad in its biggest territorial stronghold.
