At least four Palestinians were killed and 10 others were wounded, two of whom are in critical condition, in Israel's latest round of airstrikes in the Gaza Strip, local health officials and witnesses said Saturday.

Two of the fatalities were youths who were killed in a missile strike while riding on a motorcycle in the Maghazi refugee camp, located in the central part of the Hamas-controlled coastal enclave, Ashraf al-Qidra, the spokesman for the Health Ministry in Gaza, said.

Two others died in a similar attack on a mosque in the Nuseirat refugee camp, also in the central Gaza Strip, he added.

At least 10 Palestinians were wounded in airstrikes that hit mosques, homes and vacant lots in the territory and two of them are in critical condition, Al-Qidra said.

The Israeli army said at least five rockets had been fired at Israel from Gaza on Saturday and put the number fired over the past 24 hours at 70.

In a statement, the Israeli military said it had attacked 33 "terrorist targets in Gaza, including places where terrorist activity is carried out, command and control centers and weapons warehouses."

A total of 1,902 Palestinians have been killed in Gaza since the start of the Israeli campaign, mostly civilians, and roughly 10,000 have been wounded, according to the Gaza Health Ministry.

Israel initiated its operation on July 8 in response to rocket attacks from Gaza by Palestinian militants.

A total of 67 people have been killed on the Israeli side, including 64 soldiers who died after Israeli launched a ground invasion on July 17. Israeli pulled out its troops earlier this week after destroying a network of Hamas tunnels used for cross-border attacks.

The latest round of fighting follows the collapse on Friday of a three-day, Egyptian-brokered cease-fire that the two sides had strictly observed.

Hamas leaders have accused Israel of dragging out the negotiation process and ignoring Palestinian demands for a lasting cease-fire, including a lifting of the blockade of the Gaza Strip, the release of Palestine prisoners and the construction of a port and airport in the coastal enclave.

Israel, for its part, says it will not negotiate while militants continue to fire rockets into its territory.

The country's delegation to indirect talks in Cairo came back to Israel on Friday and has no immediate plans to return, according to local media.

The head of a delegation of Palestinian negotiators, Azzam al-Ahmad, said Saturday in Cairo that it would welcome direct dialogue with Israel but that its demands are "clear and absolute."
