The UN Security Council has released a statement strongly condemning a mortar attack by Syria on a Turkish border town that killed five people.
The Security Council demanded that "such violations of international law stop immediately and not be repeated."
It said: "This incident highlighted the grave impact the crisis in Syria has on the security of its neighbours and on regional peace and stability."
The 15-member council called on the Syrian goverment to "fully respect the sovereignty and territorial integrity of its neighbours".
The mortar attack happened on Wednesday and Turkey responded by striking targets in Syria later the same day and on Thursday.
The Turkish parliament has passed a bill saying it will approve military strikes against Syria if necessary but has stopped short of declaring war on its neighbour.
