Egyptian warplanes on May 26 carried out air-strikes on what President Abdul Fattah al-Sisi called six "terrorist training camps" in Libya after a new massacre of Coptic Christians earlier in the day. The latest of a series of bloody attacks on Copts in Egypt came as Christians were headed to the Saint Samuel Monastery, near the city of Minya, some 220 kilometers south of Cairo. Masked gunmen cut off the bus in three pick-up trucks, and opened fire before fleeing the scene. At least 28 people were killed, many of them children. The retaliatory air-strikes apparently struck locations of the Mujahedeen Shura Council in Libya's eastern city of Derna. (Al Arabiya, BBC News, France24, Egyptian Streets, Al Jazeera)

Over the past month, air-strikes carried out by the US and its coalition partners in Syria have killed the highest number of civilians on record since the bombing campaign began in September 2014, according to the UK-based Syrian Observatory for Human Rights. A total of 225 civilians, including 36 women and 44 children, were killed in the period between April 23 to May 23 by the Observatory's count. At least 122 ISIS fighters and eight members of militias loyal to the Syrian regime were also killed in US-led strikes over the same period.

The human rights situation in Belarus has seen a dramatic deterioration, according to a report published May 22 from Miklos Haraszti, the UN Special Rapporteur on Belarus. The report notes numerous instances of rights abuses, beginning with the suppression of peaceful protests in March over a law (PDF) imposing a tax on people who are not employed full-time, in which more than 900 people were detained. Among those detained in the March protests were political opponents, civil activists, human rights defenders, journalists and foreign observers. This wave of mass arrests was the most severe repression of human rights since the contested election of 2010. Before the new crackdown, there were reports of political opponents, social activists, and human rights defenders being harassed.

Following days of protests and strikes, Colombia's largest port city of Buenaventura exploded into violence May 19 as police opened fire on demonstrators, leaving one dead and many wounded. Marches have since continued in the city in defiance of a curfew, and scores have been detained. The protests are part of a regional campaign over harsh conditions on Colombia's Pacific coast. Buenaventura is one of South America's most important ports, yet half the city's 400,000 residents have no access to potable water. The protests began in Chocó department, up the coast from Buenaventura, under the slogan "Down with Colombia's corrupt oligarchy!" Strike leaders charge that millions of dollars in infrastructure investment for the region have disappeared.

The FARC rebels are on "high alert" following a May 17 ruling by Colombia's Constitutional Court, striking down congressional "fast track" authority for legislation related to the country's peace process. Under "fast track" rules, Colombia's Congress could only vote to approve or deny reforms related to implementing the peace process, rather than debating and voting on each point individually. The ruling comes two weeks before after "D+180," the date marking 180 days from the start of the FARC demobilization process, by which time it was slated to be complete. (InSight Crime, May 19; TeleSur, May 18, Semana, May 17)

Mexico's northeastern border state of Tamaulipas—just across from Texas' Gulf Coast—has for years been engulfed in an under-reported war, as the Gulf Cartel and its rogue offspring the Zetas battle for dominance over the narco-trafficking "plaza" (zone of control). The current flare-up in the border town of Reynosa may signal a turning point. Street gun-battles have become so common in the town that authorities have instituted a color-coded alert system to warn citizens. The town has been on "red alert" repeatedly over the past days, and there are signs that the long struggle is entering an endgame.

Turkish police on May 16 arrested two sisters and deported them to Saudi Arabia after receiving a formal complaint from their family living in the kingdom. The complaint was lodged by their father in March, claiming they are ISIS loyalists. Areej and Ashwaq al-Harby pleaded for help in a video that went viral on social media as they were being taken to a Turkish police station by immigration officers. In the video, they said their abusive family has been spreading lies to get them deported. The sisters, who fled Saudi Arabia in February, were seeking for asylum in Turkey, fearing they will be criminally charged and face execution if returned to their home country. (India Today, May 17)

As the votes came in on Iran's May 19 elections, populist hardliner Ebrahim Raeesi reluctantly accepted incumbent president Hassan Rouhani's 57% victory, after a bitter campaign. The rhetoric was so heated that a week before the poll, Rouhani even challenged Raeesi, a sitting judge, to issue an arrest warrant for him. Media organizations affiliated with Iran's hardliners, like Tasnim and Fars, went to bat for Raeesi, publishing rumors about the death of Rouhani's son 20 years ago, alleging the apparent suicide was carried out with the father's personal firearm and calling for a new investigation. Meanwhile, Basiji pro-regime militia forces (which played a critical role in violence following the disputed 2009 elections) attacked a number of Rouhani campaign offices in Tehran, Mashhad, Qazvin, Babolsar and Isfahan.
