Israel has called on the Security Council to issue a "clear and resolute" message against rockets fired from the Gaza Strip, in a letter to the United Nations that was made public on Wednesday.
The December 21 letter, made public by Israel's foreign ministry, comes amid rising tensions on Israel's border with the coastal enclave.
On Tuesday, Israel launched a series of airstrikes against what it said were tunnels, training sites and weapons facilities in the Gaza Strip, in response to a salvo of mortar shells on Monday and rocket fire on Tuesday morning.
"The incidents of the past several days are part of an escalation of attacks emanating from Gaza that target Israeli civilians, towns, and military personnel," said the letter signed by Meron Reuben, Israel's UN ambassador.
"Israel holds the de facto authority in the Gaza Strip completely responsible for all of these incidents, which are carried out in clear violation of international law. In response to such attacks, Israel has exercised and will continue to exercise its right to self-defense."
