► A terror probe involving the FBI and counterterrorism units from around the world was launched this weekend into the disappearance of a missing Malaysia Airlines Flight MH370 jet, which vanished during its route from Kuala Lumpur to Beijing on Saturday, the South China Morning Post reported. The entire passenger list was being scrutinized as Malaysian officials worked to verify the identities of all those on board. Foreign ministries earlier revealed that at least two tickets on the flight had been booked with stolen passports. Electronic records showed the two passengers who were traveling on stolen passports bought their tickets from the same Thai travel agency. And despite the efforts of 34 planes, 40 ships, and search crews from 10 countries, officials had not found any sign of the airliner as of early Monday.

Residents proclaimed their loyalty to Ukraine or Russia in competing rallies, which produced some scuffles. In Kiev, the Ukrainian capital, thousands of people poured onto the streets to mark the birthday of Taras Shevchenko, their country’s most famous poet and an ardent nationalist. Laying flowers at a statue of Shevchenko, acting Prime Minister Arseny Yatsenyuk declared that he would not give up “one centimeter of Ukrainian land.”
