British Foreign Secretary William Hague considered on Sunday that gains made by the regime in the Syrian conflict this week made it harder to organize a peace conference and to make it a success.

He said it was "worrying and depressing" that the so-called Geneva talks were not taking place this month, reiterating that the world must do more for Syria.

“The regime has gained ground on the ground, again at the cost of huge loss of life and the indiscriminate use of violence against the civilian population," Hague claimed, in reference to the decisive battle which took place between the Syrian Army and terrorists in Al-Qusayr, leaving large numbers of casualties in the ranks of the latter.

“That makes the Geneva conference harder to bring about and to make a success. It makes it less likely that the regime will make enough concessions in such negotiations, and it makes it harder to get the opposition to come to the negotiations,” Hague added.

“The way the position on the ground is changing in Syria at the moment isn't helping us bring about a political and diplomatic (solution),” he said.

Asked if he believed the Geneva talks would happen at all, Hague said: "We're working on that. We're in intensive discussions with the US and of course with Russia and the UN about this.”
