Israel has seen an increase in rocket attacks from Gaza in recent weeks.
Terror groups are using the strip to target southern Israeli cities like Ashkelon and Ashdod.
But a top Israeli military spokesperson told CBN News the range of those rockets now reaches even further.
"In 2000, the range of the average rocket was 4 to 6 kilometers and only 30,000 Israelis ... were under the risk of the rockets. Today, 11 years later, we're talking about a range of 40 kilometers," said IDF spokeswoman Lt. Col. Avital Leibovich.
"This is half an hour drive from Tel Aviv and 1 million Israelis are under this danger," she added. "Which means that they have between 50 to 55 seconds to go to shelters when the alarm is heard. And this is an unbearable situation for us."
The terrorist group Hamas controls Gaza. The Palestinian Islamic Jihad group has also been behind some of the recent rocket attacks emanating from the region.
Both organizations are funded and supplied by Iran.
