After President Donald Trump's inauguration, Mexico saw a wave of angry protests against his proposed border wall, with more than 20,000 marching in Mexico City on Feb. 12, chanting "Pay for your own wall!" But now this wave of anger is crystalizing around concrete legal initiatives that could be very problematic for the White House. First, the front-runner for next year's Mexican presidential election, the left-populist Andres Manuel López Obrador, has filed a complaint with the Inter-American Commission on Human Rights against the proposed wall.

The International Court of Justice (ICJ) on Feb. 2 ruled that it has the authority to adjudicate a dispute over a stretch of water in the Indian Ocean that is potentially laden with oil and gas. Somalia asked (PDF) the ICJ to rule on the dispute in 2014 after negotiations with Kenya broke down over the 100,000-square mile stretch. The ICJ rejected Kenya's claim that a 2009 agreement (PDF) between the two countries to settle the dispute through negotiations deprives the court of jurisdiction in the matter. Kenya's attorney general, Githu Muigai, stated: "Kenya maintains the view that litigation can resolve only one aspect of a wide range of complex issues the parties must agree upon." This decision allows the case to proceed, with no date set as of yet for the trial to begin.

According to official John McKissick at the United Nations High Commissioner for Refugees on Nov. 24, members of the Rohingya community have been subjected to numerous atrocities by troops in Burma, including execution, rape, starvation and forced displacement. McKissick said the widespread violence is part of an ongoing effort by the Burmese government to "ethnically cleanse" the Muslim minority group from the country. Speaking to the BBC from the UNHCR headquarters in Cox's Bazar, Bangladesh, McKissick said the latest increase in violence against the Rohingya is in response to the murder of nine border guards in Burma on Oct. 9, which some Burmese politicians have blamed on a Rohingya militant group.

Security forces in western Uganda arrested Omusinga (King) Charles Wesley Mumbere of Rwenzururu Nov. 27 amid claims he was harboring militants seeking independence for the semi-autonomous region. Heavy fighting broke the day before in the regional seat of Kasese, after royal guards attacked a police patrol, leaving 14 officers and some 40 guardsmen and associated militants dead. The king's palace was set afire during the two-hour battle, and a cache of weapons seized. President Yoweri Museveni had phoned the king that morning and ordered him to disband the guards, who are accused of leading a militia seeking an independent "Yiira Republic," straddling the border of Uganda and North Kivu in the Democratic Republic of Congo.

Two missiles fired from territory held by Houthi rebels in Yemen fell just short of a US warship patrolling the Red Sea, the Navy said Oct. 10.  The attack took place just north of the Bab al-Mandab Strait, which connects the Red Sea to the Gulf of Aden. The destroyer USS Mason had been "conducting routine operations in international waters," the Pentagon said in a statement. A day earlier, the Arab coalition fighting the Houthis accused the rebels of firing a ballistic missile toward the southwestern Saudi city of Taif. The missile was one of two that the Saudi-led coalition intercepted that day, the coalition said. Both attacks were apparent retaliation for an Oct. 8 air-strike by the Saudi-led coalition that killed at least 140 and wounded over 500 at a funeral in Sanaa. In the aftermath of the strike, Yemen's ex-president Ali Abdullah Saleh—who has allied his loyalist forces with the Houthis—called for a mobilization along the Saudi border "to take revenge."

Pakistan and Afghanistan agreed June 20 to peacefully resolve a border dispute after clashes and a tense stand-off over Islamabad's plan to build a barbed-wire separation barrier at its Torkham border crossing. Fighting broke out on June 12, leading to fatalities on both sides—including two children on the Afghan side of the line. The crossing, in Pakistan's Khyber Agency, was re-opened afrter both sides agreed to de-escalate following a high-level meeting in Islamabad. Tensions began in April, when Pakistani authorities demolished the homes of some 300 Afghan families living in Torkham to clear way for the "gate," as the barrier is being called. The houses were bulldozed after a number of Afghan nationals refused to comply with a four-day deadline to vacate the area and cross into Afghanistan. The families protested that they had legal residency, and that the expulsions were being carried out improperly.

The governments of Ethiopia and Eritrea are blaming each other in the weekend's deadly border skirmish that threatens a return to open war between the regional rivals. Ethiopia's Information Minister Getachew Reda described the clashes as "an Eritrean initiative." In a short statement, the Eritrean regime said Ethiopia had "unleashed an attack against Eritrea on the Tsorona Central Front. The purpose and ramifications of this attack are not clear." (BBC News) The independent exile-based Gedab News, which covers Eritrea, says it has received "credible information" that the battle was triggered when a group of Eritrean conscripted soldiers crossed the border to Ethiopia in an attempt to desert, and were shot at by Eritrean troops. Members of an armed Eritrean opposition group hosted by Ethiopia returned fire before Ethiopian soldiers then entered the fray. (Awate.com)

Thousands marched in Cairo on April 15 to protest President Abdel Fattah al-Sisi's decision to turn two disputed islands over to Saudi Arabia. Crowds chanted slogans such as "Sisi – Mubarak," "We don't want you, leave," and "The people want the downfall of the regime"—the iconic slogan of the Arab Revolution. Security forces responded with tear-gas; at least 25 were detained and are being held on charges of violating Egypt's controversial anti-protest law. More protests are planned for this weekend, and on April 22 security forces carried out pre-emptive arrests of noted activists in an apparent effort to head them off. Cafes in downtown Cairo were raided and activists seized from their homes, prisoners' rights group Freedom for the Brave said in a statement on Facebook. Pre-emptive arrests were also reported in Alexandria and in Gharbeyyia governorate.
