"Are there any survivors?" shouted Said al-Najma, as he tried to shift the blocks of concrete strewn across the road after another night of Israeli bombings that reduced houses to rubble.

Seven multi-storey buildings in the Al-Maghazi refugee camp in the centre of the Gaza Strip were razed in the strikes on Saturday night, killing 45 people, according to the Hamas-run health ministry.

Among them are four of video-journalist Mohammed Alaloul's children, as well as four of his brothers, and several of his nieces and nephews.

US Secretary of State Antony Blinken made a surprise visit to Baghdad on Sunday following a trip to the occupied West Bank earlier in the day.

Iraqi Prime Minister Mohamed Shia al-Sudani met Blinken, the premier's office said, with the two expected to discuss the risks of escalation in Israel's war with Hamas.

Blinken's visit -- which came after a brief stop in Cyprus to discuss a possible maritime aid route to Gaza -- was not announced in advance for security reasons.

Around the landmark mosque in the Jenin camp for Palestinian refugees, scenes of spiking violence in the occupied West Bank play out in rhythmic fashion.

Israeli forces make increasing raids, militants battle them in the streets, and posters of the dead are papered over pictures of previous "martyrs", as the tempo of a decades-old conflict is supercharged by the Israel-Hamas war.

"When there are funerals in the mosque, generally, sermons are given that talk about love, compassion and peace among people," Ismail Jaradat, imam of the prayer hall, told AFP.

Four relatives of a journalist were killed on Sunday in an Israeli strike in southern Lebanon, the official Lebanese news agency said, adding that the journalist was also wounded.

The border area between the two countries has seen regular exchanges of fire, in particular between Iran-backed group Hezbollah and Israel, since the start of the Israel-Hamas war triggered by the Palestinian group's October 7 attacks.

The National News Agency (NNA) said the four victims are the sister of radio correspondent Samir Ayoub and her three grandchildren, aged 10, 12 and 14.

Turkish police Sunday fired tear gas to disperse a pro-Palestinian rally staged outside a military base housing US forces just hours before the arrival in Ankara of Washington's top diplomat.

The protest outside the Incirlik Air Base in southeastern Turkey was organised by the IHH humanitarian relief fund, which in 2010 led a flotilla to Gaza that sparked Israeli raids in which 10 civilians died.

An AFP photographer said the police intervened when the crowd began to walk toward the base after holding a peaceful rally in Incirlik.

A German citizen abducted in Dubai and sentenced to death by Iran is almost unable to walk and talk due to health conditions that prison authorities have failed to properly treat, his daughter told AFP.

Jamshid Sharmahd, who is also a US resident, suffers from Parkinson's disease and could die due to his deteriorating health, Gazelle Sharmahd told AFP after her father last week made a rare phone call from prison to the family.

US Secretary of State Antony Blinken said Gazans "must not be forcibly displaced", speaking on a surprise visit Sunday to the Israeli-occupied West Bank to meet Palestinian president Mahmud Abbas.

It was the top US diplomat's first visit to the Palestinian territory since war erupted between Israel and Hamas following the October 7 attack that killed 1,400 people on Israeli soil, mostly civilians, according to Israeli officials.

Israel said Sunday it was pounding Gaza with "significant" strikes after cutting it in two, as America's top diplomat pressed a Middle East tour focused on humanitarian aid for the Palestinians.

Israeli forces "have encircled Gaza City... Now there exists a south Gaza and a north Gaza", army spokesman Daniel Hagari said.

Shortly before the strikes, internet and telephone lines were cut, and the strikes would continue over night and in the days to come, he added.

Israel pressed its war to crush Hamas on Sunday nearly a month after the worst attack in the country's history, as the Palestinian group said strikes on a central Gaza refugee camp killed dozens.

Fighting continues to rage in densely populated Gaza, despite calls for a ceasefire from Arab countries and desperate civilians after 30 days of war.

Since a shock Hamas attack on October 7, which Israeli officials say has killed 1,400 people, mostly civilians, Israel has bombarded the besieged Gaza Strip.

Israelis, deeply divided since Benjamin Netanyahu returned to power last year, have united against Hamas in war, but experts predict the veteran leader will be fighting for his survival when the conflict ends.

In the shock that gripped Israel after Hamas's October 7 attacks, the country has closed ranks behind the military operation that the 74-year-old ordered to "crush" the Palestinian militants.
