Syrian army pauses for Astana peace talks after skirmishes with Israel on southern border

Combat operations in Syria’s south have been suspended for three days as a new round of peace talks in the Kazakh capital of Astana get underway, the Syrian army’s general command has said.

Rebel leaders, however, have already accused government forces of breaching the ceasefire by bombing the towns of Deraa and Naima since the agreement went into effect at midday on Sunday ahead of the Tuesday talks.

The Syrian air force reportedly dropped barrel bombs – banned under international law because they cause indiscriminate damage over a large area. No comment was forthcoming from the military.

The second Russian, Iranian and Turkish brokered peace talks in Astana in May resulted in the creation of de-escalation zones across the country, including Syria’s south. However, the region has increasingly been targeted by government air strikes, and ground fighting has extended towards the borders with Jordan and Israel.

Stray rocket fire has led the Israeli army to launch strikes against Syrian army outposts in the south-west, where the Iranian-backed Hezbollah has a strong presence.

A rebel official told Reuters the latest ceasefire is a ploy to “drag the opposition to Astana”.

Rebel forces have already expressed deep misgivings about the de-escalation zones, which they say benefit the Syrian army by freeing forces to allow them to make territorial gains elsewhere – efforts they say are aided by Damascus’s ally Russia. Several factions are expected to boycott the talks.

Elsewhere in Syria, Arab and Kurdish forces have managed to penetrate the Old City walls of the northern Isis-held city of Raqqa, US Central Command said on Monday night.

“Coalition forces supported the Syrian Democratic Forces’ (SDF) advance into the most heavily fortified portion of Raqqa by opening two small gaps in the Rafiqah Wall that surrounds the Old City,” a statement said.

The US-backed fighters pierced Raqqa from the south for the first time on Sunday, crossing the Euphrates River to enter a new part of the Syrian city, the UK-based Syrian Observatory for Human Rights said.

The SDF has spent months tightening its siege around Raqqa, but now fighting has begun it earnest it appears the city will fall quicker than Isis’s Iraqi capital of Mosul. When the militants are ousted from Raqqa the so-called caliphate will effectively be over, although pockets of fighting continue in Iraq and Isis has also besieged the Syrian city of Deir Ezzor.

Analysts expect the group to morph into a full-blown insurgency across the two countries, and for Isis to step up terror attacks around the world in future
