Hamas tightened its grip on Gaza's ruined cities Tuesday, launching a crackdown and executing alleged collaborators, even as US President Donald Trump vowed to disarm the group.

The Israeli military said the remains of four more hostages held in Gaza had been brought into Israel, a day after Hamas handed over the bodies of four other captives and released the last 20 surviving hostages.

Hamas published a video on its official channel showing the street execution of eight blindfolded and kneeling suspects, branding them "collaborators and outlaws".

(Reuters) -Congo and the M23 rebel group signed an agreement on Tuesday for the monitoring of an eventual "permanent ceasefire", a step towards potentially ending fighting in eastern Congo, according to sources on both sides and a copy seen by Reuters.

The agreement is a sign of progress in Qatar-mediated talks after the two sides missed an August 18 deadline to finalise a peace deal.

CAIRO/JERUSALEM (Reuters) -Hamas fighters tightened their grip in Gaza on Tuesday after carrying out public executions, defying Israel's assertion that war cannot end under U.S. President Donald Trump's plan until the militants are disarmed.

LONDON (Reuters) -An Afghan national was jailed for five years on Tuesday after he was found guilty of making a threat to kill Nigel Farage, the leader of the populist Reform UK party which leads opinion polls in Britain.

Fayaz Khan was last week convicted by a jury at London's Southwark Crown Court of a single count of making a threat to kill Farage in a TikTok video posted in October 2024.

GAZA (Reuters) -As the Gaza war dragged on, a diminished Hamas faced growing internal challenges to its control of Gaza from long-standing rivals, many of them affiliated with powerful local clans.

Since Friday's ceasefire took hold, Hamas has sought to reassert itself, killing dozens of opponents in a crackdown after appearing to get a U.S. nod to temporarily police the shattered enclave.

The following are some of the key clans and figures whose members have clashed with Hamas forces over the past two years.

DUBAI (Reuters) -Iran's foreign ministry on Tuesday criticised U.S. President Donald Trump's call for dialogue, accusing Washington of "hostile and criminal behaviour" after his remarks to Israel's parliament about being ready to strike a deal with Tehran.

The ministry said in a statement that Trump's call for peace is in conflict with his actions towards Iran.

"Mr. Trump can either be a President of Peace or a President of War, but he cannot be both at the same time," Iran's Foreign Minister Abbas Araqchi said in a separate comment on X on Tuesday.

GENEVA (Reuters) -The International Committee of the Red Cross said on Tuesday that it will take time to hand over the remains of hostages and detainees killed in the Israel-Hamas war, calling it a "massive challenge" given the difficulties of finding bodies amid Gaza's rubble.

"That's an even bigger challenge than having the people alive being released. That's a massive challenge," said the ICRC's spokesperson Christian Cardon, adding it could take days or weeks and that there was a possibility they were never found.

The United Nations and the international Red Cross called on Tuesday for all crossings into Gaza to be opened to allow desperately needed aid into the Israeli-blockaded Palestinian territory.

The fragile truce in war-ravaged Gaza, introduced under US President Donald Trump's plan, needs to see crossings opened to flood the famine-hit territory with aid, they said.

MOSCOW (Reuters) -The Kremlin on Tuesday said it welcomed U.S. President Donald Trump's desire to focus on the search for a peace settlement to end the conflict in Ukraine after achieving a ceasefire in Gaza.

Kremlin spokesman Dmitry Peskov told reporters that Russia remained open to talks and hoped that the U.S. could bring its influence to bear on Ukraine in pursuit of a peace deal.

GENEVA (Reuters) -There are promising early indications from countries, including the United States as well as Arab and European states, about their willingness to contribute to the $70 billion cost of rebuilding Gaza, a United Nations Development Programme official said on Tuesday.

“We’ve had very good indications already," UNDP's Jaco Cilliers told reporters at a press conference in Geneva, without giving details. He estimated that the two-year Israel-Hamas war had generated at least 55 million tons of rubble.
