The Syrian army and allied forces pounded rebel-held areas of the southwest as thousands of civilians fled to safer opposition held areas along the border with Jordan and Israel, aid workers and rebels said.
They said hundreds of families with their personal belongings had arrived in the last two days in the towns of Tayba and Mataiyah, just a few kilometers from the heavily patrolled border with Jordan.
Busra al Harir, Nahta, Maliha and a sting of towns and villages east of Deraa city have borne the brunt of a ramped up assault by the Syrian army begun last week. It is targeting opposition areas in the strategic region bordering Jordan and the Israeli-occupied Golan Heights.
Thousands of Syrians also fled frontline opposition-held villages of Masahra and Hara in the Quneitra province to makeshift camps near the border with Israel, where Syrian artillery avoid shelling, two residents said.
The army’s offensive threatens to wreck a de-escalation zone agreed by the United States and Russia last year and risks drawing Washington deeper into the war.
