Millions of students around the world skipped school on Friday for a global climate change strike. The movement included more than 5,000 demonstrations in 156 countries, including Germany, Nigeria, and Tokyo. Young demonstrators held signs that read, “You are destroying our future,” and “There is no planet B.” In the United States, organizers expect more than 800 events. New York City Public Schools said parents could excuse their students to participate in the strike.

The United States confirmed that a drone attack in the eastern Nangarhar province of Afghanistan on Thursday likely struck some civilians. Local officials said at least 30 pine nut farmers died and 40 others sustained injuries in the attack. The strike targeted an Islamic State hideout, but the United States will work with local officials “to determine whether there was collateral damage,” said Col. Sonny Leggett, spokesman for the American-led coalition in Afghanistan.

Iran’s foreign minister on Wednesday warned of “all-out war” if Saudi Arabia retaliates for Saturday’s attack on its oil infrastructure. Iran denied involvement in the drone strikes, which temporarily halved Saudi oil production rates. Mohammad Javad Zarif told CNN that Iran “won’t blink to defend our territory” if it faces any military confrontation. President Donald Trump said Tuesday that U.S. intelligence has reason to believe Iran was behind the attack. United Nations Secretary-General António Guterres said an international team of experts was headed to Saudi Arabia to investigate.

An extended political crisis is developing in Israel after a second election yielded another deadlock between the two major political parties. Preliminary results on Wednesday showed Prime Minister Benjamin Netanyahu’s Likud party landed 31 seats in the 120-seat parliament and Benny Gantz’s Blue and White party won 32.

A week set aside to remember the victims of Afghanistan’s 18-year civil war opened with bad news: Peace talks between the United States and the Taliban failed. On Sept. 7, President Donald Trump announced that all chances of a deal with the Taliban were “dead” following multiple attacks that killed one U.S. soldier and many civilians.

Afghan President Ashraf Ghani escaped uninjured from a suicide bombing Tuesday, but 24 people died in the attack at one of his campaign rallies. The attacker rammed his motorcycle into the entrance of the gathering in the northern city of Charakar. A local official said the casualties included many women and children. Hours later, the extremist group struck again near the U.S. Embassy in the capital city of Kabul, killing at least 22 people, according to an Afghan official. On Monday, NATO confirmed a U.S. service member was killed in action.

Israelis returned to the polls on Tuesday for a snap election in the absence of a clear governing majority. Prime Minister Benjamin Netanyahu’s Likud party won the most seats in parliament in April but could not get other parties to join it to form a majority coalition.
