5 things to know for May 17: US and Iran, Taiwan, pregnant woman killed, SAT tests, Canada and the Philippines

1. US and Iran

The United States says it has multiple images of Iranian commercial ships in the Persian Gulf that it believes are carrying missiles. An official told CNN that recent surveillance has shown some of the ships moving in and out of Iranian ports in the recent days. CNN hasn't reviewed the intelligence that led to this assessment. And the government hasn't provided any proof the ships are carrying hidden missiles or any other munitions. All this comes as the United States has moved bombers and a carrier strike group into the region. Fears of a potential military conflict between the countries have increased over the past couple of weeks. Officials in Washington are debating whether Iran is planning to attack US assets or whether it is acting defensively in an attempt to deter US action.

Taiwan legalized same-sex marriage today, becoming the first place in Asia to pass such legislation. Lawmakers took up the controversial issue after the island's Constitutional Court ruled that the existing law -- which said marriage was between a man and a woman -- was unconstitutional. The bill passed today goes into effect at the end of next week. Gay rights seemed to have regressed in the rest of Asia. Homosexuality is legal in mainland China, but prejudices and discrimination persist under the Communist Party. And just last month, Sultan Hassanal Bolkiah, the ruler of Brunei, said he'd introduce death by stoning for those convicted of gay sex. (He later walked that back.) More than two dozen countries around the world allow same-sex marriage, according to the Pew Research Center.

3. Pregnant woman killed

Police arrested and charged three people in a ghastly killing of a pregnant teen in Chicago. Marlen Ochoa-Lopez, 19, disappeared late last month after she went to receive an offer of free baby clothes from a woman she had communicated with online. Ochoa-Lopez's body was found Tuesday in a garbage can in the backyard of the woman who had offered the clothes. She had been strangled and her unborn baby forcibly removed from her womb, police said. The baby is in grave condition at a hospital. Two people, including the woman who police say lured the teen to the home, were charged with murder, while a third person was charged with concealment of a crime. Here are some safety tips to remember if you're meeting someone to buy or sell items in online transactions.

4. SAT tests

Students who come from tough backgrounds just might catch a break the next time they take the SAT. The College Board, the nonprofit group that runs the standardized test, said it will start assigning a score to students who take the SAT to reflect their social and economic backgrounds. The Environmental Context Dashboard would factor in things such as crime and poverty in a student's neighborhood to capture their "resourcefulness to overcome challenges and achieve more with less." This dashboard score will not include a student's race. College admissions are under heightened scrutiny after indictments were handed down against wealthy and powerful parents who allegedly paid their kids' ways into elite universities.

5. Canada and the Philippines

Canada and the Philippines are feeling some kind of way about each other right now. The two countries are having a diplomatic squabble -- over trash. And not just any old trash, mind you. They're fighting about 6-year-old trash. The tensions have gotten so bad that the Philippines has recalled its ambassador to Canada. This trash tiff started in 2013 when more than 100 containers of material from Canada arrived in the Port of Manila. It was supposed to be recyclable plastic; it turned out to be nonrecyclable plastic, household waste and diapers. Now Canada is accused of violating an international treaty governing the transport of hazardous waste. The Philippines wants the garbage gone, and President Rodrigo Duterte has threatened to ship it all back and "throw them into the shores or beach of Canada."
