Millions of Americans from New Mexico to the Carolinas are bracing for a potentially catastrophic ice storm that could crush trees and power lines and knock out power for days, while many northern states all the way to New England could see enough snow to make travel nearly impossible, forecasters say.

An estimated 100 million people were under some type of winter weather watch, warning or advisory on Wednesday ahead of the storm, the National Weather Service said.

Landslides hit a house and a campground in New Zealand on Thursday, leaving at least two dead while emergency crews were trying to rescue others buried in rubble, officials said.

The first hit a house in the community of Welcome Bay on New Zealand's North Island at 4:50 a.m., police said. Two people escaped the house, and the bodies of two who were trapped inside were recovered hours later, Emergency Management Minister Mark Mitchell said.

The U.S. military said Wednesday it has started transferring detainees from the Islamic State group being held in northeastern Syria to secure facilities in Iraq.

The move came after Syrian government forces took control of a sprawling camp, housing thousands of mostly women and children, from the U.S.-backed Syrian Democratic Forces, or SDF, which withdrew as part of a ceasefire. Troops on Monday seized a prison in the northeastern town of Shaddadeh, where some IS detainees escaped and many were recaptured, state media reported.

Israeli forces on Wednesday killed at least 11 Palestinians in Gaza, including two 13-year-old boys, three journalists and a woman, hospitals said, on one of the war-battered enclave 's deadliest days since the ceasefire between Hamas and Israel took effect in October.

The United States is trying to push the deal forward and implement its challenging second phase.

President Donald Trump on Wednesday scrapped the tariffs that he threatened to impose on eight European nations to press for U.S. control over Greenland, pulling a dramatic reversal shortly after insisting he wanted to get the island "including right, title and ownership."

In a post on his social media site, Trump said he had agreed with the head of NATO on a "framework of a future deal" on Arctic security, potentially defusing tension that had far-reaching geopolitical implications.

Iran offered its first government-issued death toll Wednesday following a crackdown on nationwide protests, giving a far lower figure than activists abroad as the country's theocracy tries to reassert control after unrest recalling the chaos surrounding its 1979 Islamic Revolution.

State television carried statements by the Interior Ministry and the Foundation of Martyrs and Veterans Affairs, an official body providing services to families of those killed in wars, saying 3,117 people were killed. It added that 2,427 of the dead in the demonstrations that began Dec. 28 were civilians and security forces. It did not elaborate on the rest. Iran's government in the past has undercounted or not reported fatalities from unrest.

European Union lawmakers on Wednesday voted to hold up ratification of a major free trade agreement with the Mercosur group of South American countries over concerns about the legality of the deal.

In a vote in Strasbourg, France, lawmakers narrowly approved sending the EU-Mercosur agreement to Europe's top court to rule on whether it is in line with the bloc's treaties. The result was 334 votes in favor to 324 against, with 11 abstentions.

Recent conflict between Syrian government forces and Kurdish fighters in northeast Syria has again brought to the world's attention the detention facilities where Islamic State group members are held and camps where mostly women and children have been locked up for years.

During the battles that the Kurdish-led Syrian Democratic Forces fought against the Islamic State group over the past decade, thousands of IS fighters of different nationalities were captured and have been held in some dozen jails in northeast Syria.

Iran's foreign minister issued the most direct threat yet Wednesday against the United States after Tehran's bloody crackdown on protesters, warning the Islamic Republic will be "firing back with everything we have if we come under renewed attack."

The comments by Abbas Araghchi, who saw his invitation to the World Economic Forum in Davos rescinded over the killings, comes as an American aircraft carrier group moves westward toward the Middle East from Asia. American fighter jets and other equipment appears to be moving in the Mideast after a major U.S. military deployment in the Caribbean saw troops seize Venezuela's Nicolás Maduro.

Prime Minister Benjamin Netanyahu of Israel said Wednesday he had agreed to join U.S. President Donald Trump's Board of Peace, after his office earlier criticized makeup of the board's executive committee.

The board, chaired by Trump, was originally envisioned as a small group of world leaders overseeing the Gaza ceasefire plan. The Trump administration's ambitions have appeared to balloon into a more sprawling concept, with Trump extending invitations to dozens of nations and hinting it will soon broker global conflicts.
