Editor's note: CNN has crews in Israel, Gaza and around the region reporting on the latest attacks, talks and fallout from the upsurge in the Gaza-Israel conflict. Here are some of their stories:

Sara Sidner in Tel Aviv

[Updated 8:35 a.m. ET Wednesday]

A bomb exploded on a bus in Tel Aviv as it passed by Israeli army headquarters around noon local time Wednesday. The attack, which police said left at least 22 people injured, shook up the Israeli public and threatened to complicate efforts to achieve a cease-fire on the eighth day of violence between Israel and Gaza.

At the scene of the bus bombing, police cordoned off the street as ambulances arrived. CNN's Sara Sidner said there is a hospital nearby. Sidner said the injured included people on the bus and people who were on the street.

The nighttime explosions in Gaza - and rocket attacks from Gaza into southern Israel - come after Egypt and Hamas had indicated that a halt, or calming, might happen around 2 p.m. ET. But Hamas and Egypt seem to have pulled back from those statements.

[Updated 2:01 p.m. ET Tuesday]

Both Wedeman and Damon report a huge blast in Gaza. The blast comes minutes before the start of what a senior Hamas official said would be a "calming down."

The Hamas official said an announcement would come from a Hamas official in Cairo at 2 p.m. ET. The "calming down" could halt violence, but is not the same as an official cease-fire or truce, Wedeman reported.

Pleitgen, in Ashkelon, Israel, says that in the past hour, he's seen rockets from Hamas intercepted by the Israeli military in the sky over southern Israel.

Reza Sayah in Egypt, near Gaza border

[Updated 11:33 a.m. ET Tuesday]

Sayah said three or four huge explosions happened about 35 minutes ago near the Rafah border crossing between Egypt and Gaza. He said he didn't know what exploded.

Sayah reported that other explosions have happened in that area over the past two days. Asked how people there react to the blasts, he said: “Frankly, they’re used to it."

"They may duck, they may look to see where it came from, they may listen to the car alarms, but by now they’re very much used to the explosions,” Sayah said.

Fred Pleitgen in Ashkelon, Israel

[Updated 10:47 a.m. ET Tuesday]

Pleitgen, reporting from Ashkelon near Israel's border with Gaza, says four or five rockets were just fired from Gaza into Israel's airspace, and that it appears Israel's military shot down all of them.

He reports that the Israel Defense Forces claims five Israeli soldiers were injured in a recent rocket strike from Gaza - information that the IDF also makes on its website. Information on where the soldiers were injured wasn't immediately available.

Anderson Cooper in Gaza City

[Updated 10:29 a.m. ET Tuesday]

Cooper reports he and his team saw a body of a man - alleged to be a spy for Israel - being dragged by a motorcycle that someone was driving along the main streets of Gaza City. The motorcycle rider was accompanied by other men on motorcycles, and the group alleged that the dead man was a spy, Cooper reports.

A rope attached the body's legs to the motorcycle, Cooper says.

[tweet https://twitter.com/arwaCNN/status/270866978313494528%5D

Damon's tweets came on a day when an Israeli official said his country is holding off on a ground offensive into Gaza, in hopes that a diplomatic solution may be achieved to halt the raging violence. But fresh rockets fired into Israel and strikes by Israel in Gaza showed there was no immediate sign of a cease-fire.
