Syrian Military Launches Counterattacks in Attempt to Halt Insurgents' Surprise Advance

New Delhi, India: The Syrian military rushed reinforcements to the country's northwest and launched airstrikes on a major city Sunday in an attempt to push back insurgents who seized the country's largest city of Aleppo in a surprise offensive in recent days.

The insurgency, led by jihadi group Hayat Tahrir al-Sham, launched their campaign on Wednesday with a two-pronged attack on Aleppo and the countryside around Idlib, before moving toward neighbouring Hama province.

On Sunday, government troops created a “strong defensive line” in northern Hama, according to Britain-based opposition war monitor the Syrian Observatory for Human Rights, as they attempted to stall the insurgents' momentum. Meanwhile, jets pounded the cities of Idlib and Aleppo, killing at least 15 people, according to a group that operates in opposition-held areas.

The surge in fighting has raised the prospect of another violent, destabilising front reopening in the Middle East at a time when Israel is fighting Hamas in Gaza and Hezbollah in Lebanon, conflicts that have repeatedly threatened to ignite an even wider regional war. It also risks drawing Russia and Turkey — each with its own interests to protect in Syria — into direct heavy fighting against each other.

The insurgents announced their offensive Wednesday, just as a ceasefire between Hezbollah and Israel began, raising some hope that tensions in the region might be calming.

The surprise offensive is a huge embarrassment for Syrian President Bashar Assad — whose forces have been fighting insurgents in a civil war since 2011. It comes at a time when his allies — Iran and groups it backs and Russia — are preoccupied with their own conflicts.

Iranian Foreign Minister Abbas Araghchi is expected in the Syrian capital of Damascus later Sunday. He told reporters that Tehran will back the Syrian government and army. Arab leaders, including Jordan's King Abdullah II and United Arab Emirates President Sheikh Mohammed bin Zayed Al Nahyan, also called Assad to express their solidarity.

Opposition troops advance The insurgents took over most of Aleppo on Saturday and made gains in the surrounding province, including capturing a military academy and a strategic town that lies on the highway linking the city with Damascus and the coast.

Elsewhere, rebel commander Col Hassan Abdulghani said the insurgents advanced in the countryside around Idlib, putting all of the province of the same name under their control. They also claimed to have entered the city of Hama, but there was no independent confirmation of that.

Abdulghani said 65 Syrian troops were taken prisoner in eastern Aleppo.

The insurgents vowed to push all the way into Damascus, but life in the Syrian capital remained normal with no signs of panic. In southeastern Aleppo, however, the main road out of the city was gridlocked as people fled the fighting, and gas stations in the area were short on fuel.

Turkey, a main backer of Syrian opposition groups, said its diplomatic efforts had failed to stop Syrian government attacks on opposition-held areas in recent weeks. Turkish security officials said a limited offensive by the rebels was planned to stop government attacks and allow civilians to return, but the offensive expanded as Syrian government forces began to retreat from their positions.

The United Nations special envoy for Syria, Geir Pedersen, said the push by the rebels poses a risk to regional security and called on resuming diplomatic efforts to end the conflict.

US national security adviser Jake Sullivan told CNN's “State of the Union” that the US, which has about 900 troops in Syria, is watching the situation carefully. The American forces, which are in the northeast and far from Aleppo, are guarding against a resurgence by the extremist Islamic State group.

The group leading the rebel advance is designated a terrorist organisation by the US, and Sullivan said Washington has “real concerns about the designs and objectives of that organisation”.

“At the same time, of course, we don't cry over the fact that the Assad government, backed by Russia, Iran and Hezbollah, are facing certain kinds of pressure,” he added.

Syrian troops fortify northern Hama as jets pound Idlib According to Syrian state news agency SANA and the Syrian Observatory for Human Rights, the army overnight pushed back insurgents in the northern countryside of Hama province.

Syrian state media said government resupply included heavy equipment and rocket launchers while Syrian and Russian airstrikes targeted weapon depots and insurgent strongholds. Pro-government radio station Sham FM said the Syrian army shot down drones belonging to Hayat Tahrir al-Sham in northern Hama.

Syrian state television claimed government forces had killed nearly 1,000 insurgents over the past three days, without providing evidence or details.

Government airstrikes in Idlib killed at least three civilians, including two children, and wounded 11 others, said the Syrian Civil Defence, known as the White Helmets, which operates in opposition-held areas.

Airstrikes also struck in and around Aleppo, including near a hospital in the city centre, killing 12 people, including at least eight civilians, according to the White Helmets and the Syrian Observatory for Human Rights.

In a call with foreign officials, Assad vowed to defeat the insurgency. “Terrorism only understands the language of force, which is the language we will break and eliminate it with, regardless of its supporters and sponsors,” he said.

The 2016 battle for Aleppo was a turning point in the war between Syrian government forces and rebel fighters after 2011 protests against Assad's rule turned into an all-out war. After appearing to be losing control of the country to the rebels, the Aleppo battle secured Assad's hold on strategic areas of Syria, with opposition factions and their foreign backers controlling areas on the periphery.
