ISLAMABAD, April 15 (Xinhua) -- Pakistan has called upon all parties involved in Syrian conflict to refrain from action that is contrary to the charter of the United Nations.

Commenting on the military strikes against Syria by the United States, Britain and France, Pakistan Foreign Ministry spokesman on Saturday showed "grave concern" at the situation in Syria.

U.S. President Donald Trump said Friday that he had ordered precise strikes on Syrian military facilities in a coordinated action with Britain and France.

"We are following the situation in Syria with grave concern. We call on all sides to refrain from actions inconsistent with the UN Charter," Pakistan Foreign Ministry spokesman Mohammad Faisal said.

Regarding the suspected use of chemical weapons in Syria, the spokesman said it is important to establish facts through urgent and transparent investigations by the Organization for the Prohibition of Chemical Weapons (OPCW).

"We call upon all parties to strive for an agreement within the OPCW framework and extend full support to the Organization," he said.

"At this time our thoughts are with the people of Syria who have suffered as a result of ongoing turmoil in that country. We hope that all parties will work to find an urgent solution to end the suffering of the Syrian people," the spokesman said.

The U.S. and British governments have said the military actions would deter future use of chemical weapons, referring to an alleged chemical attack in Douma, a Syrian suburb northeast of capital Damascus, on April 7.
