JERUSALEM (AP) — Israel was drawn into the Syrian civil war for the first time on Sunday, firing warning shots into the neighboring country after a stray mortar shell fired from Syrian territory hit an Israeli military post.

The Israeli military said the mortar fire caused no injuries or damage at the post in the Golan Heights, which Israel captured from Syria in the 1967 Mideast war and then annexed. But in recent weeks, incidents of errant fire from Syria have multiplied, leading Israel to warn that it holds Syria responsible for fire on Israeli-held territory.

"A short while ago, a mortar shell targeted an IDF (Israel Defense Forces) post in the Golan Heights," said army spokeswoman Lt. Col. Avital Leibovich. "We answered with a warning shot toward Syrian areas. We understand this was a mistake and was not meant to target Israel and then that is why we fired a warning shot in retaliation."
