JERUSALEM (JTA) — Israel filed a complaint with the United Nations Security Council against Syria and Lebanon over the breach of its border by protesters.

The delegation said Monday it filed the complaint in the Security Council and with the U.N. Secretary-General’s office for violation of international law.

The complaint follows demonstrations on Sunday for Nakba Day, or Catastrophe Day, marking Israel’s achieving statehood. Israeli troops fired on protesters from Syria, Lebanon and Gaza who tried, and in some cases succeeded, in breaching Israel’s border.

As many as four Syrian protesters and up to 10 Lebanese protesters were killed during the infiltration attempts.

Also Monday, Lebanon’s delegation filed a complaint against Israel over the Lebanese deaths, citing "Israel’s disregard for Lebanese sovereignty and U.N. resolutions."
