Ukrainian President Poroshenko said on Thursday Russian forces had been "brought into Ukraine" and he called an urgent meeting of Ukraine's security and defense council to decide the next steps to take in the crisis. "I made the decision to cancel a working visit to the Republic of Turkey in connection with the rapidly deteriorating situation in Donetsk region, in particular in Amvrosiyivka and Starobesheve, as Russian troops have actually been brought into Ukraine," he said in a statement on the presidential website.
The sister of the accused Boston Marathon bombers was arrested in New York City for threatening a woman over the phone, saying she could "put a bomb on you," police said on Wednesday. Aliana Tsarnaev, 23, sister of Dzhokhar and Tamerlan Tsarnaev, was facing charges of aggravated harassment, a New York City Police Department spokesman said. Tsarnaev, of North Bergen, New Jersey, was accused of calling a woman in New York City's Harlem neighborhood and telling her "I have people that can go over there and put a bomb on you," the spokesman said. Her brothers are accused of killing three people and wounding more than 260 after detonating pressure-cooker bombs near the finish line of the Boston Marathon on April 15, 2013.
