According to The Times of Israel, Israel defence forces chief of staff Gadi Eisenkot made a trip to Brussels last Thursday to meet General Curtis Scaparrotti, head of the U.S. army's European command, to discuss Iranian influence in Syria. "We recently returned from the region, where we heard concerns from our close ally, Israel, about Iranian operations in Syria", some 43 congressmen said in the letter.
Israeli Defense Minister Avigdor Lieberman said in a statement, "We hold the Syrian regime responsible for any firing or breach of sovereignty and call on it to hold back all players active in its territory".
More than 400 people were killed and tens of thousands left homeless by the quake that struck on the Iran-Iraq border late on Sunday.
The letter came a day after American officials said that U.S. has been arming Iranian-linked militia and anti-Daesh envoy appointed during former U.S. President Barack Obama's tenure, Brett McGurk played a significant role in it.
The official map included in a preliminary agreement that seeks to establish buffer zones in southwest Syria indicates that Iran-backed forces could deploy within several miles (kilometers) of the Israeli frontier - setting the stage for potential conflict between the bitter enemies.
Israel Offers Arch Enemy Iran Aid After Earthquake Kills Hundreds
At the time, the IDF Spokesperson's Unit claimed that the military is prepared to intervene in the Syrian war in order to prevent the takeover of the town out of its commitment to the Druze community.
"We will simply not enable a Shiite and Iranian presence in Syria, and will not allow all of Syria to become a forward operating base against the state of Israel".
"We offered Iran assistance after earthquakes in the past, but they refused".
Israeli Prime Minister Benjamin Netanyahu on Tuesday said that he offered aid through the Red Cross for the victims of the deadly 7.3 magnitude natural disaster that struck the Iraq-Iran border region on Sunday. "The Jewish people are among the leaders in human morality and compassion", he tweeted in Hebrew.
