Hundreds of air strikes were unleashed by Syrian and Russian forces over the southern province of Daraa, after negotiations to ceasefire failed on Wednesday.

Contrary to the Syrian Regime’s demands, rebel factions refused to surrender, which resulted in an escalation to an already intense firefight-crisis.

The Syrian Observatory for Human Rights was unable to verify casualties, but confirmed that "more than 600 air strikes between raids and bombardment took place last night, targeting the towns of Taiba, Naima, Saida, Umm Al-Mayden and Al-Yawdouda in the city of Daraa near the Jordanian border."

Observatory Director Rami Abdel Rahman told AFP that the bombardments haven't been this intense since the beginning of the military campaign two weeks ago. He added that the reason behind this is to "make the rebels back down after they refused to subject themselves to the Russian terms for a ceasefire."

On Wednesday, the Jordanian Minister of Foreign Affairs and Expatriates, Ayman Safadi, visited Moscow to negotiate the southern Syrian conflict with his Russian counterpart Sergey Lavrov. The two discussed the current humanitarian crisis in hopes of reaching a ceasefire deal with Syrian rebel factions.

Jordan’s mediation efforts aimed to achieve a political solution through a proposed truce that would result in normalizing the situation or, at least, easing the conflict.

During the joint press conference in Moscow, Safadi stressed the need for an immediate solution, as more than 270,000 Syrians have recently fled their homes in order to escape the imminent danger of the firefights in Daraa and its nearby areas.

Safadi explained that a political settlement is vital for ensuring the security, safety and dignity of the Syrians on their land, adding that Jordan will remain committed to helping Syrians whom Jordanians have "opened [their] hearts, homes, schools and hospitals" to.
