A group of anti-war protesters held a small demonstration outside an air force base used as the main starting point for bombing runs on the Gaza Strip to call for an end to the military offensive.

The 15 demonstrators, dressed in white overalls daubed with blood-red paint, held up signs outside the Hatzor air base near Beersheba calling to “Stop the Gaza in massacre” and “Stop the siege.”

Other signs read “Bombing civilians won’t bring a solution” and “The blood of children is on your hands,” Channel 2 reported on Tuesday.

Security forces briefly detained some of the protesters before releasing them.

An unnamed protester said the group was objecting to what is being done by the government ostensibly on behalf of all of Israel’s citizens.

“We came here to express our opposition to Israel for an attack which is done in our name,” she said. “Entire neighborhoods have been deleted in Gaza and southern Israel residents live in fear that no force or weapons will not be able to solve. We are calling for an end to the attack on Gaza, lifting the blockade and genuine dialogue.”

Another protester said: “What is provocative is to make corpses, not to dress as corpses.”

Over 1,100 Palestinians have been killed during the three-week operation, according to Gazan health officials, including hundreds of Hamas fighters.

Israel launched the operation on July 8 to stymie rocket fire and destroy tunnels used to infiltrate into Israel. Fifty-three Israeli soldiers have been killed, as well as two civilians and a Thai national.

Several thousand left-wing activists gathered in Tel Aviv’s Rabin Square on Saturday evening, calling for an end to bloodshed in the Gaza Strip and a return to negotiations with the Palestinians.
