JERUSALEM, July 24 (Xinhua) -- Israeli missiles shot down Tuesday a Syrian fighter jet that entered its aerial space, Israel's military said.

"Two Patriot missiles were launched at a Syrian Sukhoi fighter jet that infiltrated into Israeli airspace," the military said in a statement.

The army said the jet was monitored all its way into Israel, and was intercepted after it infiltrated about 2 km into Israeli airspace.

"Since morning hours, there has been an increase in the internal fighting in Syria, including an increase in the activity of the Syrian Air Force," the statement said.

The military warned it will continue to operate against the breach of the 1974 Separation of Forces Agreement.

The incident came a day after Israel's Prime Minister Benjamin Netanyahu met in his Jerusalem office with a Russian delegation led by Foreign Minister Sergei Lavrov and Chief of General Staff of the Armed Forces Valery Gerasimov.

The meeting was also attended by Israel's Defense Minister Avigdor Liberman, Israel Defense Forces Chief-of-Staff Lt.-Gen. Gadi Eisenkot.

Netanyahu reportedly rejected a Russian proposal to withdraw Iranian forces 100 km from Syria's disputed border with Israel.
