Syria says it targeted an Israeli vehicle that crossed a ceasefire line into its territory earlier this week because it was heading toward a village with a large rebel presence.

In a letter to the U.N. Security Council circulated Friday, Syria's U.N. Ambassador Bashar Ja'afari said his country exercised its right to self-defense and would respond immediately to any other violation of its sovereignty and territorial integrity.

Syria accused Israel of violating the U.N. Charter and the separation of forces agreement that followed the 1973 Arab-Israeli war when it sent the vehicle into Syrian territory and launched two missiles on Tuesday.

Israel said an Israeli jeep came under fire during an overnight patrol on its side of the cease-fire line in the Golan Heights.
