ALEPPO, Syria, Jan 9 (Reuters) - Kurdish groups in Aleppo vowed to defend their neighbourhoods from government forces on Friday, rejecting ceasefire terms declared by Damascus that demand Kurdish fighters withdraw from the Syrian city where clashes have raged this week.

The violence in Aleppo has exposed a deep faultline between President Ahmed al-Sharaa's Islamist-led government and Kurdish forces, which have resisted its efforts to bring their fighters under centralised authority.

Tear gas burning his eyes, his voice hoarse from shouting anti-government slogans as cars honked around him, Majid joined crowds of Iranians taking to the streets in defiance of a crackdown on a swelling protest movement.

He used a pseudonym for security reasons and like all those who spoke about the protests was reached by AFP journalists outside Iran.

Majid described how he rallied with hundreds of others in the streets of eastern Mashhad on Wednesday night, even as police tried to disperse the crowd that nonetheless kept reforming.

Jan 9 (Reuters) - Somalia's foreign affairs ministry said on Friday that China's top diplomat Wang Yi had postponed his planned visit to the East African country.

RAMALLAH, West Bank, Jan 9 (Reuters) - The former U.N. envoy expected to help lead Donald Trump's so-called Board of Peace for Gaza met a top Palestinian Authority official on Friday as the U.S. president pushes ahead with his plan for the enclave's future.

Trump is expected to announce the composition of the board this month, possibly as early as next week, a U.S. official said. Portrayed as part of a transitional government, the board is an important component of Trump's phased plan to halt the war between Israel and Hamas.

DUBAI, Jan 9 (Reuters) - Yemen's main southern separatist group has decided to disband, one of its members said in a statement broadcast on state media on Friday in Saudi Arabia, where a delegation from the group, which appears to be splitting, has been attending peace talks.

There was no immediate comment from those members of the separatist group - the Southern Transitional Council (STC) - who are not taking part in the Riyadh talks, which were aimed at ending a crisis between Gulf powers Saudi Arabia and the United Arab Emirates over developments in Yemen.

Iranians took to the streets in new protests Friday to press the biggest movement against the Islamic republic in more than three years, as authorities sustained an internet blackout as part of a crackdown that has left dozens dead.

On Friday, US President Donald Trump said it looked like Iran's leaders were "in big trouble" and repeated an earlier threat of military strikes if peaceful protesters are killed.

"It looks to me that the people are taking over certain cities that nobody thought were really possible just a few weeks ago," Trump said.

Jan 9 (Reuters) - Kurdish councils in Syria's Aleppo said on Friday they would not evacuate neighbourhoods under their control as part of a ceasefire deal to end days of fighting between Kurdish forces and Syrian government fighters.

In a statement published by Syrian Kurdish outlets, the local councils of the Ashrafiyah and Sheikh Maksoud districts said calls to leave Aleppo were "a call to surrender" and that Kurdish forces would instead "defend their neighbourhoods".

DUBAI, Jan 9 (Reuters) - Iran was largely cut off from the outside world on Friday after authorities blacked out the internet to curb expanding protests, with phone calls not reaching the country, flights cancelled and online Iranian news sites only intermittently updating.

Supreme Leader Ayatollah Ali Khamenei accused protesters of acting on behalf of U.S. President Donald Trump, saying rioters were attacking public properties and warning that Tehran would not tolerate people acting as "mercenaries for foreigners".

Jan 9 (Reuters) - Iran's Supreme Leader Ali Khamenei will give a speech in a few minutes on "the terrorist actions" in the country, Iranian state TV reported on Friday, as protests over economic hardships continued around the country.

Iranians staged their biggest protests yet of an almost two week movement sparked by anger over the rising cost of living, chanting slogans including "death to the dictator" and setting fire to official buildings, videos showed Friday.

Internet monitor Netblocks said authorities had imposed a total connectivity blackout late Thursday and added early Friday that the country has "now been offline for 12 hours... in an attempt to suppress sweeping protests".
