Relations between Turkey and Israel have hit their "lowest level" amid the Israeli assault on the Gaza Strip, and may not be able to improve for some time, Turkish Deputy Prime Minister Bulent Arinc said.

Arinc, one of the founding members of Prime Minister Recep Tayyip Erdogan's Islamist-influenced AKP party, said Turkey had always calibrated its relations with Israel according to Israel's behavior towards the Palestinians.

Thousands of Jordanians took to the streets of Amman and other cities Friday to support Hamas and condemn Israel's offensive in Gaza, where more than 800 Palestinians have been killed.

Around 2,000 people demonstrated in central Amman after Friday midday prayers, chanting: "We sacrifice our blood and souls for you, Gaza," in support of Hamas' armed wing the Ezzedine al-Qassam Brigades.

As Ahmed Bulbul's body is brought into the emergency room at Gaza's Shifa hospital, a father standing nearby clamps his hand over his little boy's eyes.

Bulbul's leg has been ripped open by shrapnel, and the exposed flesh wobbles as he is taken into the chaotic emergency room at the Gaza City hospital.

French police have banned a protest against Israel's Gaza offensive that was due to take place in Paris on Saturday, following several similar rallies that turned violent.

The ban, announced by police on Friday, comes in the wake of clashes earlier this month at pro-Palestinian demonstrations in which some protesters shouted anti-Semitic slogans and fought with police. 

Israeli security forces were on heightened alert Friday after several Palestinians were shot dead during a huge protest in the West Bank against Israel's military offensive in Gaza.

Palestinian medical and security sources told Agence France-Presse that five Palestinians were killed in the West Bank on Friday in two separate incidents involving both Israeli troops and Israeli settlers.

The World Health Organization urged on Friday the creation of a humanitarian corridor in the besieged Gaza Strip to allow for the evacuation of the wounded.

"WHO is calling for the creation of a humanitarian corridor ... to reach various crossings and to help in the evacuation of the large number of injured people," said Paul Garwood, a spokesman for the U.N. health agency.

U.S. Secretary of State John Kerry huddled Friday with U.N. chief Ban Ki-moon and Egypt's foreign minister as pressure built for a ceasefire in Gaza.

Kerry, who spent another night in Cairo reaching out by telephone to regional officials, met Ban and Egyptian Foreign Minister Sameh Shoukri for around half an hour.

Palestinian Islamist movement Hamas said Friday it fired three rockets at Tel Aviv airport, a day after U.S. and some European airlines had resumed flights after a two-day suspension.

"At 11:45 am (0845 GMT), the Qassam Brigades bombarded Ben Gurion airport with three M75 rockets," a statement from Hamas's armed wing said.

Turkey's foreign minister flew into Qatar Friday amid mounting U.S. calls on the two Western allies to use their influence with Palestinian movement Hamas to end the bloodshed around Gaza.

U.S. Secretary of State John Kerry, who has been spearheading Western efforts to end the Palestinian territory's deadliest violence since 2008-9, has repeatedly telephoned both Qatari and Turkish leaders in an effort to broker a truce.

Iranians rallied nationwide on Friday in a show of support for Palestinians as arch-foe Israel pursued its deadly campaign against the Gaza Strip.

Demonstrations were held in Tehran and more than 700 towns and cities across the country on the last day of prayer and rest of the Muslim holy fasting month of Ramadan, state television reported.
