GAZA CITY, Gaza Strip - A spokeswoman confirms that the Israeli military has called up 16,000 reservists ahead of possible Gaza invasion.
The news comes after a Palestinian rocket flew over Tel Aviv on the third day of an Israeli military operation against the Gaza Strip.
Sirens wailed across the city Friday afternoon shortly before the explosion sounded out.
Police spokesman Micky Rosenfeld says no injuries have been reported and it appears the rocket landed in the Mediterranean.
It was the second straight day that Gaza militants have targeted Tel Aviv. The attacks, which Israel considers to be a major escalation, could draw an Israeli ground invasion of Gaza closer.
On Friday, Israel offered to suspend its offensive in the Gaza Strip during a brief visit by Egypt's premier there if militants refrain from firing rockets at Israel, an official said, but the Palestinians unleashed a fresh salvo.
An official in Prime Minister Benjamin Netanyahu's office said the Israeli leader was responding to an Egyptian request.
Gaza militants stepped up their barrages of rocket fire into Israel as Hesham Kandil crossed into Gaza before midday through the only border post with Egypt, heavily guarded by Egyptian security personnel wearing flak jackets and carrying assault rifles.
He was greeted by Gaza's Hamas prime minister, Ismail Haniyeh, who ventured out in public for the first time since Israel launched the offensive Wednesday by assassinating the militant group's military commander.
