"I think we need … to understand that there is no military solution, the solution is political. And the way for a political solution is known - it is the Resolution of the Security Council 2254, with a Communique in Geneva and it is through intra-Syrian talks between government and opposition to be able to overcome the differences that exits,” Guterres said Saturday, Press TV reported.
The UN chief admitted, however, that "there is still a long way to go to bring together the members of the Security Council in relation to the Syrian conflict."
He made the remarks in southern Sweden, where he met with UN Security Council ambassadors for an informal working meeting.
Gustavo Meza-Cuadra, Peru's UN ambassador and current president of the Security Council, said the meeting could help the ambassadors "narrow the difference" in their stances towards Syria.
Britain's UN Ambassador Karen Pierce promised they would work "their hardest" to find solutions.
“I don't know that it can be resolved that easily. It's a very intractable and difficult issue and the war has been running for a very long time. Too long. But I think what we can assure you of is that we will try at our hardest," said Pierce.
Talks ‘bombed’ by West
Russian Foreign Minister Sergei Lavrov said on Friday the US and its allies "bombed" the UN-backed Syria peace talks in Geneva by their recent military strikes against the country.
The US, France and Britain "on 14 April bombed not only made-up chemical sites in Syria, but also bombed the (UN-backed peace) talks in Geneva," Lavrov said following a meeting with UN envoy for Syria Staffan de Mistura in Moscow.
"We came very close to a re-launching of the Geneva process with a real dialogue between Syrians, mainly on the question of constitutional reform," Lavrov noted.
On April 14, the US, France and the UK carried out missile attacks on a number of targets in Syria in response to a suspected chemical attack in the Syrian town of Douma, near Damascus, that reportedly took place on April 7. Syria has rejected any role in the alleged attack, which is yet to be investigated.
Violation of international law
Jurists at the German parliament have said the recent US-led airstrikes in Syria over violated international law.
"The use of military force against a state, as a sanction against the violation of an international convention by this state, is an infringement of the prohibition of the use of violence in international law," experts at Bundestag, Germany’s lower house of parliament, said in reply to a question filed by the far-left Die Linke party.
The experts referred in particular to the United Nations declaration from their 1970 General Assembly, which stresses "the duty of States to refrain in their international relations from military, political, economic or any other form of coercion aimed against the political independence or territorial integrity of any State".
The UN Security Council had also rejected armed retaliation, stressing that it is "incompatible with the objectives and the principles of the United Nations."
The experts also said the UK's declared motive for joining the US in the airstrikes on Syria was "not convincing."
Britain's Prime Minister Theresa May said it was "legally and morally right" for the UK to join the attack on Syria to prevent "further human suffering".
