Venezuela's re-invigorated opposition faces a crucial test Wednesday as it seeks to fill streets nationwide with protesters in an appeal to the military and the poor to shift loyalties that until recently looked solidly behind President Nicolas Maduro's socialist government.

The protests have been called to coincide with a historic date for Venezuelans — the anniversary of the 1958 coup that overthrew military dictator Marcos Perez Jimenez. Government supporters are also expected to march in downtown Caracas in a rival show of strength.

The United Nations' envoy to the Mideast said Tuesday that peacekeepers in Lebanon have not been given access to tunnels stretching into Israel, which U.N. officials say violate a case-fire resolution that ended a devastating war between Israel and Hizbullah in 2006.

Nikolay Mladenov told the Security Council that the U.N. peacekeeping mission known as UNIFIL has confirmed that two tunnels crossed the U.N.-drawn Blue Line between Lebanon and Israel, but "has not been granted access to the confirmed entry points of a tunnel near Kfar Kila on the Lebanese side."

A report by Moody's Investors Service that downgraded Lebanon's long-term investment ratings reflects the need for quickly forming a new government and implementing reforms, caretaker Finance Minister Ali Hassan Khalil said on Tuesday.

Khalil's statement came in a tweet after Moody's downgraded the Lebanon's issuer ratings to Caa1 from B3. The outlook was changed to stable from negative.

Russian police detained a drunken man who threatened the crew of a passenger plane flying Tuesday from a Siberian city to Moscow, forcing it to land shortly after take-off.

The Russian Investigative Committee said that the man told the Aeroflot crew that he was armed and demanded the diversion of the plane after it had taken off from the Siberian city of Surgut. The plane landed in the city of Khanty-Mansiysk, about 230 kilometers (145 miles) to the west.

Tens of thousands of Palestinians are no longer getting food aid or basic health services from America, U.S.-funded infrastructure projects have been halted, and an innovative peace-building program in Jerusalem is scaling back its activities.

The Trump administration's decision last year to cut more than $200 million in development aid to the Palestinians is forcing NGOs to slash programs and lay off staff as the effects ripple through a community that has spent more than two decades promoting peace in the Middle East.

Qatar said on Monday that it plans to invest $500 million in Lebanon government bonds, the Qatari News Agency said on Twitter on Monday.

Thirty-one days into the partial government shutdown, Democrats and Republicans appeared no closer to ending the impasse than when it began, with President Donald Trump lashing out at his opponents after they dismissed a plan he'd billed as a compromise.

Trump on Sunday branded House Speaker Nancy Pelosi a "radical" and said she was acting "irrationally." The president also tried to fend off criticism from the right, as conservatives accused him of embracing "amnesty" for immigrants in the country illegally.

The only total lunar eclipse this year and next came with a supermoon bonus.

On Sunday night, the moon, Earth and sun lined up to create the eclipse, which was visible throughout North and South America, where skies were clear. There won't be another until the year 2021.

The anti-government protests rocking Sudan for the past month are reminiscent of the Arab Spring uprisings of nearly a decade ago. Demonstrators, many in their 20s and 30s, are trying to remove an authoritarian leader and win freedoms and human rights.

Activists challenging President Omar al-Bashir's autocratic rule say they have learned from their Arab Spring counterparts and introduced tactics of their own. That and their persistence appear to pose a real threat to the 29-year rule of the general-turned-president.
