Jerusalem is revered as holy by Christians, Muslims and Jews alike.

Just a few hours later, the Israeli government approved the recruitement of 75,000 reserve soldiers, according to Israel's Channel 2 News. 

It is the third day of Operation Pillar of Defense, and tensions have been rising with constant bombing of southern Israeli towns. Another missile shot at Tel Aviv and the first war siren was heard in Jerusalem. The missile fell near Jerusalem in an area closer to a Palestinian village than to Israeli settlements, and there were no reports of injury, Israel's Yediot Acharonot reported. 

"We are communicating a simple message," said Abu Ovadia, a spokesman for the Hamas military wing, according to Yediot Acharonot. "There is no Zionist security anywhere on the land of Palestine, and we are planning additional surprises."

Jerusalem's residents are still in shock. 

"We were scared," said Rotem Sasson, a 20-year-old living in Jerusalem. "Who thought the sirens would reach Jerusalem? We thought they would never bomb this area because they have an important mosque in the area."

When she heard the war siren for the first time in her life, Sasson and her family ran toward a protected area, and waited for further instructions in the news.

"I guess all we can do is go into war shelters and pray that everything will be okay," she said. 

While Israeli Prime Minister Benjamin Netanyahu began to process an approval to recruit 75,000 soldiers to invade the Gaza strip earlier today, many of Sasson's friends have already been recruited.

After the second war siren was heard in Tel Aviv, and a missile fell near a small airport in the northern part of the city, residents begin to digest the meaning of the situation.

"We haven't completely changed our everyday routine here, but it's a stressful situation," said Micky Weinstein, a Tel Aviv resident. "But we still feel that, at any given moment, everything can change here."

After a missile hit Tel Aviv, the city's municipality opened community war shelters for the use of residents, according to Yediot Acharonot. 

Following the escalating violence, Egyptian President Mohamad Morsi visited Gaza earlier, and later made it clear that he sides with the Palestinians, Israel's Haaretz reported.
