The Israel Defense Forces shot down a Syrian drone on Friday that had crossed into the demilitarized zone between the two countries in the second such incident of the week.

“With the completion of an investigation into the incident by the air force, it was determined that the Patriot battery intercepted the Syrian unmanned aerial vehicle that was operating in the buffer zone,” said the Israeli Air Force.

According to the IDF, the Syrian drone had crossed into the demilitarized buffer zone established by a 1974 cease-fire agreement following the 1973 Yom Kippur War.

“The IDF will continue to take action against attempts to violate the 1974 Separation of Forces Agreement [and] will not allow violations of Israeli sovereignty,” the army said in a statement.

Earlier this week, the IDF shot down a Syrian drone that had infiltrated several miles into Israeli air space. In retaliation, the Israeli Air Force carried out airstrikes on three government targets in southern Syria.
