More than 850 family members of victims of the 9-11 attacks filed a lawsuit (PDF) March 20 against the Kingdom of Saudi Arabia, alleging that the Saudi state provided support to al-Qaeda in multiple ways. First, it alleges that Saudi Arabian charities ran terrorist training camps in Afghanistan, working hand-in-hand with Osama bin Laden. The suit also claims that the Saudi government directly aided al-Qaeda by providing passports and transportation across the globe. Finally, the suit contends that certain Saudi officials worked with the hijackers in the US for the 18 months leading up to the attacks. The suit seeks unspecified damages, with the primary motive to hold Saudi Arabia accountable for the attacks.

Seven army officers have been arrested and charged with war crimes in the Democratic Republic of Congo (DRC), according to government officials at a press conference on March 18. The charges stem from a massacre of unarmed civilians in Kasaï-Central Province in February that was recorded and widely shared on social media. Congolese military auditor general Joseph Ponde Isambwa said that all seven arrested soldiers were members of the Armed Forces of the Democratic Republic of Congo, or FARDC. Ponde said the charges against the officers include "war crime by murder, war crime by mutilation, war crimes by cruel inhuman and degrading treatment and denial of an offense committed by persons subject to military jurisdiction."

Two federal judges—one in Maryland on March 16 and another in Hawaii the day before—issued temporary restraining orders (PDF, PDF) against President Donald Trump's new 90-day travel ban. Finding that the state had established a strong likelihood of success on the merits, Hawaii District Judge Derrick Watson issued an opinion permitting continued travel from six predominantly Muslim countries listed on Trump's order. Trump responded to the order, calling it "the bad, sad news," and "an unprecedented judicial overreach." The new order, which dropped Iraq from the banned countries list, would have barred entry for nationals from Iran, Libya, Somalia, Sudan, Syria and Yemen for 90 days, and completely banned entry of refugees for 120 days.

The Colombian Senate on March 13 approved a transitional justice structure that will attempt to bring reparations to the more than 8 million victims of the decades-long conflict between the Colombia government and the Revolutionary Armed Forces of Colombia (FARC). The new system will include a Transitional Justice Tribunal, a Truth Commission and a Missing Persons section, all aimed at punishing war crimes and gaining reparations for victims. The vote was 60-2 in the Senate, with all 40 members of the Democratic Center party boycotting the vote. The bill must now be approved by Colombia's Constitutional Court before it can take effect.

Massachusetts Attorney General Maura Healey declared on March 9 that Massachusetts will be joining fellow states in suing President Donald Trump to block his new travel ban executed earlier in the week. Trump's new executive order has removed Iraq from the former list of travel-restricted countries and suspended the refugee program for 120 days. Healey stated that the second ban, despite such changes, remains discriminatory and unconstitutional. Massachusetts will join Washington, Hawaii, Oregon, and New York in requesting Judge James Robart to apply his previous travel ban suspension to the revised ban. Washington Attorney General Bob Ferguson recently stated that the new ban still violates the Equal Protection Clause of the US Constitution. Despite legal challenges, the revised ban is scheduled to take effect on March 16.

The New York Police Department (NYPD) reached a new settlement on March 6 over its surveillance of Muslims after a federal judge rejected an earlier deal in October. The new settlement would create greater oversight of the NYPD's intelligence-gathering programs by a civilian representative. In the original rejection of the case, the judge stated that the agreement did not ensure that the NYPD would be limited in how it could monitor political and religious activity. Zachary Carter, head of New York City's law department, said that the new settlement agreement addresses the judge's previous concerns.

US President Donald Trump signed a new immigration executive order March 6, which contains several departures from the original January executive order. Notably, Iraqi citizens are no longer ineligible to receive new visas. The order also sets out classes of people eligible to apply for case-by-case waivers to the order, including those who were previously admitted to the US for "a continuous period of work, study, or other long-term activity," those with "significant business or professional obligations" and those seeking to visit or live with family. However, the other six Muslim-majority countries listed on the original ban will continue to be blocked from obtaining new visas. Furthermore, the refugee program will be suspended for 120 days, and will accept no more than 50,000 refugees a year, down from the 110,000 set by the Obama administration. The order will take effect on March 16.
