(Reuters) -Thousands of protesters against Israel's war in Gaza marched in New York City on Friday as Israeli Prime Minister Benjamin Netanyahu visited to address the U.N. General Assembly.

Protesters waved Palestinian flags, wore keffiyeh scarves and carried banners reading "Free Palestine," "stop starving Gaza" and "Arms embargo now," video showed.

They gathered in Times Square, across town from the United Nations building, before marching to the U.N.

"Netanyahu you can't hide, we charge you with genocide," they chanted.

Greek Prime Minister Kyriakos Mitsotakis, a key partner of Israel within the European Union, warned Friday that Israel risked losing remaining friends with its destructive war in Gaza.

Addressing the UN General Assembly, the center-right Greek leader said Israel had a right to self-defense after the October 7, 2023 attacks by Hamas but cannot "justify the death of thousands of children."

"Greece maintains a strategic partnership with Israel, but this does not prevent us from speaking openly and frankly," Mitsotakis said.

WASHINGTON (Reuters) -Ukrainian President Volodymyr Zelenskiy this week asked U.S. President Donald Trump for Tomahawk missiles to force Russian President Vladimir Putin to make peace, Axios reported on Friday.

The request came during Zelenskiy and Trump's meeting alongside the United Nations General Assembly, according to the report, which cited a Ukrainian official and another source familiar with the two leaders' meeting. Zelenskiy told Axios in a separate interview taped Wednesday that he had requested long-range weapons.

BEIRUT (Reuters) -Lebanese authorities will on Friday release former central bank governor Riad Salameh, who posted a record-high bail after nearly 13 months in detention over alleged financial crimes committed during his tenure, a Lebanese judicial source said.

Once viewed as the linchpin of the banking system, Salameh, 74, saw his standing crumble as a 2019 meltdown of the sector he oversaw impoverished Lebanese depositors and froze most out of their accounts. He was subsequently battered by corruption allegations both in Lebanon and abroad.

UNITED NATIONS (Reuters) -The world must not allow Iran to rebuild its nuclear and military programs, Israeli Prime Minister Benjamin Netanyahu said on Friday, a day before the United Nations is set to reimpose sanctions on Tehran.

All U.N. sanctions on Iran are due to be reimposed at 8 p.m. EDT on Saturday (0000 GMT) after European powers, known as the E3, triggered a 30-day process accusing Tehran of violating a 2015 deal meant to prevent it from developing a nuclear weapon.

Former UK prime minister Tony Blair could take a leading role in a transitional authority for Gaza under US-led peace plans, various British media reported on Friday.

It follows Blair's involvement in discussions with the administration of US President Donald Trump and others over the post-war transitional body for the Palestinian territory.

The plan could involve Blair leading the authority with the support of the UN and Gulf nations, according to the BBC and The Economist magazine.

CAIRO/GENEVA (Reuters) -Since Israel shut a vital corridor into famine-stricken northern Gaza before escalating its ground offensive this month, community kitchens and health clinics have closed and vital flows of food have slowed, residents and U.N. agencies say.

The Zikim Crossing was shut on September 12, days ahead of an Israeli ground offensive on Gaza City in the north of the territory, prompting warnings from aid agencies.

UNITED NATIONS (Reuters) -Prime Minister Benjamin Netanyahu, speaking at the United Nations on Friday, vowed to continue Israel's war against Hamas in the Gaza Strip and told the hostages still held by the Palestinian militants they were not forgotten.

Speaking in Hebrew, the Israeli leader said: "We've not forgotten you - not even for a second."
