Congolese security forces on Tuesday tried to slow the advance of Rwanda-backed M23 rebels who say they have captured Goma after entering eastern Congo's largest city, as U.N. officials reported an unspecified number of bodies on the streets.

Hospitals are overwhelmed in Goma, while hundreds of thousands are fleeing gunfire and shelling, the officials said.

An explosion struck a Hong Kong-flagged container ship Tuesday traveling north through the Red Sea, sparking a major fire that forced its crew to abandon the vessel, shipping industry officials said.

The ship was drifting and ablaze some 225 kilometers (140 miles) off the coast of Hodeida, a port city in Yemen held by the country's Houthi rebels, said the Diaplous Group, a maritime firm.

(THE CONVERSATION) For more than a decade, Syrians have been the world's largest refugee population.

Israeli Prime Minister Benjamin Netanyahu is hoping to meet with President Donald Trump in Washington as early as next week, according to two U.S. officials familiar with preliminary planning for the trip.

Should the trip come together in that timeframe, Netanyahu could be the first foreign leader to meet with Trump at the White House since his inauguration last week. The officials, who spoke on condition of anonymity because the planning remains tentative, said details could be arranged when Trump's special Middle East envoy, Steve Witkoff, travels to Israel this week for talks with Netanyahu and other Israeli officials.

A delegation of Russian officials arrived in Damascus on Tuesday for the first such visit to Syria since the fall of former President Bashar Assad.

Assad, an ally of Moscow, took refuge in Russia after his ouster in December in a lightning rebel offensive.

They walked for hours loaded with whatever clothes, food and blankets they could carry. Many smiled, some hugged loved ones they hadn't seen for months. Hundreds of thousands of Palestinians filled Gaza's main coastal road as they streamed back to homes in the north.

The mood was joyous, even though many knew their homes had been destroyed in Israeli offensives against Hamas that leveled large parts of Gaza City and the surrounding north.

Hezbollah chief Sheikh Naim Qassem has announced that the ceaesfire agreement's violation by Israel "highlights Lebanon's need for the resistance," adding that so-called army-people-resistance equation is "still steadfast despite the talk of haters."

In a pre-recorded speech aired Monday, Qassem added that his group won’t accept the extension of the ceasefire deadline, without addressing the fact that the Lebanese government had already done so overnight.

Israeli authorities say they have arrested two Israeli citizens for allegedly conducting missions on behalf of Iran, the latest in a string of similar cases announced in recent months.

A statement from the Israeli police and the Shin Ben internal security agency on Monday said that Yuri Eliasfov and Georgi Andreev, residents of northern Israel, were in contact with an Iranian agent and carried out various missions under his instruction.

U.S. President Donald Trump's suggestion that Egypt and Jordan take in Palestinians from the war-ravaged Gaza Strip was met with a hard "no" Sunday from the two U.S. allies along with the Palestinians themselves, who fear Israel would never allow them to return.

Trump floated the idea on Saturday, saying he would urge the leaders of the two Arab countries to take in Gaza's now largely homeless population, so that "we just clean out that whole thing." He added that resettling most of Gaza's population of 2.3 million could be temporary or long term.

Tens of thousands of Palestinians returned to the most heavily destroyed part of the Gaza Strip on Monday as Israel lifted its closure of the north for the first time since the early weeks of the 15-month war with Hamas in accordance with a fragile ceasefire.

Massive crowds of people carrying their belongings on foot stretched along a main highway running next to the coast in a stunning reversal of the mass exodus from the north at the start of the war, which many Palestinians had feared Israel would make permanent.
