Two Chicago police officers were killed Monday after being struck by a metro train, authorities said.Conrad Gary and Eduardo Marmolejo were responding to a shots fired call on the city's South Side when a passing train hit them, Chicago police Superintendent Eddie Johnson told reporters.The officers were searching an area near train tracks at 103rd Street and Cottage Grove Avenue when they were struck, Johnson said. The train had been traveling at 60 mph to 70 mph, he said."While doing the most dangerous thing any police officer can do, and that is to chase an individual with a gun, these brave young men were consumed with identifying a potential threat to their community and put the safety of others above their own," Johnson said.A suspect was ultimately taken into custody and a gun was recovered, Johnson said.Gary, 31, had been on the force 18 months. Marmolejo, 37, joined the department 2 1/2 years ago, Johnson said.The men, both fathers, lost their lives just a week before Christmas."This holiday will never be the same for those two families," Chicago Mayor Rahm Emanuel said. "And while our hearts are with them, we lost people who answered the call to make Chicago a better place. We go about our lives not thinking twice and we can do that because of the men and women in the Chicago police department."Johnson asked Chicago to pray for the families of the officers, and for the men and women of the officers' 5th district, "who, even tonight, would stop at nothing to safeguard their community," he said."This has been an immensely difficult year for the Chicago police department," Johnson said, "And especially for the men and women of the 5th district where they have faced tragedy after tragedy this year." 1746

Two people have been bitten by sharks off the coast of North Carolina in the past 14 days, and a third person was bitten by an unknown animal during that time period, officials said.On Sunday, an 8-year-old boy was bitten by an animal "believed to be a shark," according to Village Manager of Bald Head Island Chris McCall.McCall says the child suffered non-life threatening injuries in the incident off Bald Head Island's South Beach.The boy had puncture wounds on his leg and was transported off the island to receive medical treatment, McCall said.McCall said authorities don't know what type of shark was involved in the attack.This is the second attack in the state in the last two weeks.A 17-year-old girl lost her left leg and two fingers on her left hand in a 780

When a robber put down his gun to count the money he demanded, a quick-thinking employee at a fireworks stand in Texas did not waste time. The worker grabbed the gun and shot him.The man, reported to be 19-years-old, had walked up to the stand on Thursday and commanded two workers behind the counter to give him money, the Harris County Sheriff's Office said. As the workers placed the cash on the counter, the suspect also put his weapon down to grab what he could.That's when one worker grabbed the gun and shot him, Harris County Sheriff's Deputy Eddie Hazel said. 580

  

White House efforts to limit access to President Donald Trump's conversations with foreign leaders extended to phone calls with Saudi Crown Prince Mohammed bin Salman and Russian leader Vladimir Putin, according to people familiar with the matter.Those calls -- both with leaders who maintain controversial relationships with Trump -- were among the presidential conversations that aides took remarkable steps to keep from becoming public.In the case of Trump's call with Prince Mohammed, officials who ordinarily would have been given access to a rough transcript of the conversation never saw one, according to one of the sources. Instead, a transcript was never circulated at all, which the source said was highly unusual, particularly after a high-profile conversation.The call - which the person said contained no especially sensitive national security secrets -- came as the White House was confronting the murder of journalist Jamal Khashoggi, which US intelligence assessments said came at the hand of the Saudi government.With Putin, access to the transcript of at least one of Trump's conversations was also tightly restricted, according to a former Trump administration official.It's not clear if aides took the additional step of placing the Saudi Arabia and Russia phone calls in the same 1314

  

When Angela Walker went through her son's school folder, she was shocked to find what the fifth grader had been working on in class.A social studies assignment from Blades Elementary School in Oakville, Missouri, had asked some students, including her biracial son, to imagine that they work in the slave trade. Then it prompted them to set a price for a slave."You own a plantation or farm and therefore need more workers. You begin to get involved in the slave trade industry and have slaves work on your farm. Your product to trade is slaves.Set your price for a slave. _____________ These could be worth a lot.You may trade for any items you'd like," one of the questions in the exercise read.That question was one among 12 that school Principal Jeremy Booker said "attempted to address market practices."Other questions asked students to set a price for items such as a bushel of grain, a piece of lumber and a jug of milk. At the end of the exercise, students were asked to reflect on a free market economy and whether they'd consider themselves wealthy given the money and items they had left over."As part of both the Missouri Learning Standards for fifth-grade Social Studies and the fifth-grade Mehlville School District curriculum, students were learning about having goods, needing goods and obtaining goods and how that influenced early settlement in America," Booker wrote in a letter sent to families at the school on Monday."Some students who participated in this assignment were prompted to consider how plantation owners traded for goods and slaves."Assignment was 'culturally insensitive'The assignment was "culturally insensitive," Booker wrote, and he said the teacher had expressed "significant remorse."As the Mehlville School District continues to investigate, the teacher has been placed on administrative leave, the district confirmed to CNN. Booker also wrote that he was working to train all teachers and staff at the school about "cultural bias.""Also, I am working with district leadership to provide all Blades teachers and staff with professional development on cultural bias in the near future," he wrote."We are working together to ensure all students and families feel valued and respected at Blades Elementary."Chris Gaines, Mehlville School District superintendent, apologized for the assignment on Tuesday."Asking a student to participate in a simulated activity that puts a price on a person is not acceptable," Gaines wrote in a statement. "Racism of any kind, even inadvertently stemming from cultural bias, is wrong and is not who we aspire to be as a school district. I am sorry and disappointed that this happened in our school."NAACP hopes to meet with school officialsWalker, who is a teacher herself, told 2765
