Palestinian militants fired a rocket aimed at Jerusalem on Friday, setting off air raid sirens throughout the city and opening a new front in three days of fierce fighting between Israel and armed groups in the Gaza Strip.
The Israeli campaign has been limited to airstrikes so far. But military officials say they are considering expanding it to a ground campaign.
Lt. Col. Avital Leibovich, a military spokeswoman, said the military had called 16,000 reservists to duty on Friday as it geared up for a possible ground offensive.
She said the army had authority to draft an additional 14,000 soldiers. She would not say where the troops were deployed.
As air-raid sirens went off in Jerusalem, witnesses said they saw a stream of smoke in Mevasseret Zion, a Jerusalem suburb.
Israeli police spokesman Micky Rosenfeld said the rocket landed in an open area near Gush Ezion, a collection of Jewish settlements in the West Bank southeast of the city.
An attack on Israel’s self-declared capital marks a major escalation by Gaza militants, both for its symbolism and its distance from the Palestinian territory. Located roughly 75 kilometers (50 miles) away from the Gaza border, Jerusalem had been thought to be beyond the range of Gaza rocket squads.
Abu Obeida, spokesman for the Hamas militant wing, said the group had fired a long-range rocket at Jerusalem.
“We are sending a short and simple message: There is no security for any Zionist on any single inch of Palestine and we plan more surprises,” he said. Hamas officials said the rocket was a homemade “M-75″ rocket, a weapon that has never been fired before.
It also marks a bit of a gamble for the militants. Gush Ezion is close to the Palestinian city of Bethlehem and just a few kilometers (miles) from the Al-Aqsa Mosque in Jerusalem’s Old City, one of Islam’s holiest sites.
Hundreds of thousands of Palestinians live in Jerusalem and nearby areas of the West Bank.
Militants already have fired rockets into the southern outskirts of Tel Aviv, another unprecedented achievement, on Thursday. The rocket attacks have not hurt anyone in the bustling metropolis, but have caused panic and jitters.
Just a few years ago, Palestinian rockets were limited to crude, homemade devices manufactured in Gaza. But in recent years, Hamas and other armed groups have smuggled in sophisticated, longer-range rockets from Iran and Libya, which has been flush with weapons since Moammar Gadhafi was ousted last year. Most of the rockets do not have guided systems, limiting their accuracy, though Israeli officials believe the militants may have a small number of guided missiles that have not yet been deployed.
