The pre-trial chamber of the International Criminal Court (ICC) on May 31 rejected a challenge by the Libyan government to the court's jurisdiction over Saif al-Islam Qaddafi, the son of Libya's deposed leader Muammar Qaddafi. The ICC ordered the Libyan government to turn over Saif al-Islam, who is currently being held in Zintan, Libya, where he is facing war crimes charges in a Libyan court. The ICC's decision dismisses a challenge filed by the Libyan government last year claiming the ICC did not have jurisdiction over the case. The court's decision found that the Libyan judicial system was not prepared to handle Saif al-Islam's trial, and thus jurisdiction falls to the ICC. The Libyan government may appeal the ICC ruling.

Syrian elite troops are backing up an offensive apparently led by Hezbollah against rebels in the strategic town of Qusayr, as the UN Human Rights Council debates a resolution condemning the assault. Russia meanwhile protests a European Union decision to lift its arms embargo on the Syrian rebels, and says it will respond by supplying Damascus with S-300 air-defense missiles. This, in turn, is decried as a "threat" by Israel, which warns it could launch air-strikes to destroy any deployed missiles. "The situation is beginning to show worrying signs of destabilizing the region as a whole," said UN rights chief Navi Pillay. 

Turkey will build a 2.5-kilometer wall along the Cilvegözü post on the border with Syria to prevent illegal crossings, Trade and Customs Minister Hayati Yazıcı announced May 23. The border crossing lies within 10 kilometers from Reyhanlı town, where a twin bomb attack killed 51 and wounded more than 100 on May 11. A protocol with the Turkish Armed Forces has already been signed for the construction of the wall, Yazıcı said.

Israeli missiles struck a research center near Damascus, setting off explosions and causing casualties, Syria's state news agency reported  May 5. If confirmed, it would be the second Israeli strike on targets in Syria in three days. Two previous Israeli air-strikes, one in January and one on May 3, targeted weapons reportedly bound for Hezbollah. (AP, May 5) On May 4, a former senior official in the Bush administration said the use of chemical weapons in Syria might have been an Israeli-instrumented "false flag operation." Retired Col. Lawrence Wilkerson, Colin Powell's former chief of staff, told Current TV: "We don’t know what the chain of custody is. This could’ve been an Israeli false flag operation, it could’ve been an opposition in Syria... or it could've been an actual use by Bashar Assad. But we certainly don’t know with the evidence we’ve been given. And what I'm hearing from the intelligence community is that that evidence is really flakey." (JP, May 4)

Egyptian police arrested 12 "Black Bloc" protesters in clashes outside Cairo's presidential palace April 27. Protesters hurled rocks and fire bombs at the walls of the presidential palace in the Heliopolis suburb, and torched a police vehicle. The clashes come days after the detainment of 22 suspected Black Bloc members on court order. On May 1, a court refused an appeal to release the young men, who have been ordered to remain in custody for a second 15-day period. On their Facebook page, the Blac Bloc say they are a "generation born of the blood of the martyrs" from the 2011 revolution that toppled Hosni Mubarak. Prosecutor general Talaat Abdallah has accused the group of "terrorism." 

The People's Protection Committees (YPG), armed wing of Syria's main Kurdish Democratic Union Party (PYD), joined forces with Syrian rebels last month, helping them overrun the strategic Sheikh Maksud neighborhood on a hilltop north of Aleppo. "We have the same goal as the rebel fighters," YPG commander Engizek told AFP last week. "It is to seek the ouster of Assad." But days later, militiamen of PYD—considered to be the Syrian offshoot of Turkey's outlawed Kurdistan Workers’ Party (PKK)—clashed with Free Syrian Army forces in the Kurdish neighborhood. The internecine fighting started after FSA rebels accused YPG forces of attacking a rebel convoy and otherwise secretly collaborating with the government. "The YPG have been on the government side from the beginning," said Khalid Alhayani, an FSA brigade commander. "When we entered [the area], we asked YPG if we could use their territory to hit government check points. They would agree but then report to the government our plans."

France has vowed to punish those responsible for the April 23 car bomb blast at its embassy in Tripoli that destroyed half the building and wounded six—two French guards, and four resident of nearby buildings that were damaged, including an 18-year-old woman who suffered spinal damage. Foreign Minister Laurent Fabius, who immediately flew to Tripoli, vowed: "The terrorists who wanted to attack France and Libya and undermine the friendship between them will pay." Prime Minister Ali Zeidan visited the scene of the devastation with Fabius. There was no claim of responsibility, but suspicion immediately fell on al-Qaeda's North African arm, AQIM, which has repeatedly threatened retaliation for the French intervention in Mali. On April 25, two suspects arrested following a lightning investigation led by a French judge and a team of foresnics experts dispatched by Paris.

The Assad regime's use of chemical weapons is announced as a "red line"—the favored metaphor of Israel's Benjamin Netanyahu, now alarmingly accepted by the US media, at least.  Israel yesterday said the line has been crossed. Brigadier-General Itai Brun, head of IDF military intelligence, told an Institute for National Security Studies conference in Tel Aviv: "There's a huge arsenal of chemical weapons in Syria. Our assessment is that the [Assad] regime has used and is using chemical weapons." Brun cited photographs of victims that showed them foaming at the mouth and with contracted pupils. "To the best of our understanding, there was use of lethal chemical weapons. Which chemical weapons? Probably sarin." And John Kerry, speaking at a NATO meeting in Brussels, called on the alliance to make preparations to respond in the event of chemical weapons threatening a member (meaning Turkey).
