No injuries or damage reported in suspected missile attack from Sinai • Explosions were away from tourist areas, and holidaymakers undeterred by blasts • Tel Aviv identifies underground garages to be used as public shelters during possible war with Iran.

Two explosions shook the southern city of Eilat on Wednesday night, startling residents but causing no injuries or damage. The explosions are believed to be the result of Grad rockets fired into Israel from Egypt´s Sinai Peninsula.

Searches continued Thursday for the remnants of the rockets.

The explosions halted a concert by popular Israeli singer Eyal Golan at Eilat´s southern beach and concert-goers were asked to leave out of concern for their safety.

The explosions were heard away from the main tourist areas, and the city´s beachfront promenade was packed with holidaymakers on Wednesday night as usual. "I don´t think anyone is getting worked up about it ... No one in the area of the hotels heard the explosions, and everyone is having fun as usual," said local resident Shirli Fahima.

Rocket fire from Sinai at the Eilat region has become an increasingly common phenomenon in recent years. On June 16, two Grad rockets landed near Mitzpe Ramon and Ovda. Islamic terrorist operatives in Sinai are suspected of being responsible for these rocket attacks and on Wednesday, a statement from the Salafi jihadist terrorist group in Sinai claimed other jihadist groups, which it did not name, were behind past attacks on Sinai´s gas pipeline that delivers gas from Egypt to Israel and Jordan and the rocket fire on Israel in recent years. Egypt had repeatedly denied that rockets had ever been fired from Sinai into Israel.

An Iron Dome anti-rocket battery was recently deployed in Eilat as part of an operational deployment program that includes changing the locations of the batteries from time to time.

Israel´s defense establishment has long been on alert to deal with the dangers posed by the growing terrorist infrastructure in Sinai. There is concern that terrorists in the region will use anti-tank and anti-aircraft missiles in their operations.

Last year, eight Israelis were killed in a multipronged terror attack on Route 12, which runs along the Israel-Egypt border north of Eilat.

In June, an Israeli civilian contractor working on the fence being constructed on the Israel-Egypt border was killedin an attack by terrorists who crossed the border from Sinai.

Over the past week and a half, Egyptian soldiers have been mounting a security sweep of Sinai in response to a lethal attack earlier this month by Islamic militants on an Egyptian military outpost in Rafah. Sixteen Egyptian soldiers were killed in that attack. The militants later stormed the Israeli border in two stolen vehicles and were killed by Israeli soldiers.

Tel Aviv parking garages to be used as bomb shelters

Against the backdrop of growing concerns over a possible war with Iran, the Tel Aviv-Jaffa municipality has been identifying underground locations that could be used as shelters during missile attacks.

The municipality announced on Wednesday that around 60 underground parking garages, totaling around 850,000 square meters, have been approved for use as shelters during emergencies. These garages could provide protection to around 800,000 people.
