(CNN) -- It's been more than three weeks since militants from the dreaded Boko Haram terrorist group dragged 276 girls out of their beds at a boarding school in northern Nigeria, and still no one knows where the girls are. International assistance has begun to flow into Nigeria, whose president has vowed to end the terror threat plaguing his country. 

Here's what you need to know to get caught up: 

Where are the girls? 

It's anyone's guess. Boko Haram's leader, Abubakar Shekau, said in a video that he was going to sell them into slavery, but it's unknown whether he has. Pentagon spokesman U.S. Navy Rear Adm. John Kirby and other officials have said they believe the girls may have been separated into smaller groups, making the task of finding them inordinately more difficult. Gordon Brown, a former UK prime minister and the U.N.'s special envoy for global education, speculated that the girls may have been moved into neighboring countries. "The search must be in Niger, Cameroon and Chad, to see if we can find information," he said. 

What's being done to find them? 

Nigeria hasn't given a lot of information about its efforts other than to say that its soldiers have been out in the field, looking for the girls. Nigerian police offered a $310,000 reward, but there's no evidence that has turned up any leads. The United States and Britain have sent advisers to help the Nigerian government find the girls, stage rescue missions and help in the larger fight to defeat Boko Haram.

(CNN) -- Det har gått mer än tre veckor sedan militanter från den fruktade Boko Haram terroristgruppen drog 276 flickor ur sina sängar på en internatskola i norra Nigeria, och fortfarande vet ingen var flickorna är. Internationellt bistånd har börjat strömma in i Nigeria, vars president har lovat att upphöra med det terrorhot som plågar hans land. Var är flickorna? Det är någons gissning. Boko Harams ledare, Abubakar Shekau, sade i en video att han tänkte sälja dem till slaveri, men det är okänt om han har det. Pentagon talesman USA:s flotta Rear Adm. John Kirby och andra tjänstemän har sagt att de tror att flickorna kan ha delats upp i mindre grupper, vilket gör uppgiften att finna dem omåttligt svårare. Gordon Brown, en före detta premiärminister i Storbritannien och FN:s särskilda sändebud för global utbildning, spekulerade i att flickorna kan ha flyttats till grannländerna. "Sökandet måste vara i Niger, Kamerun och Tchad, för att se om vi kan hitta information," sade han. Vad gör man för att hitta dem? Nigeria har inte gett mycket information om sina ansträngningar annat än att säga att dess soldater har varit ute på fältet och letat efter flickorna. Nigerianska polisen erbjöd en belöning på 310 000 dollar, men det finns inga bevis som har hittat några ledtrådar. USA och Storbritannien har skickat rådgivare för att hjälpa den nigerianska regeringen att hitta flickorna, iscensätta räddningsuppdrag och hjälpa till i den större kampen för att besegra Boko Haram. 1. Hur många tjejer? 2. Vem tog dem? 3. Var var de innan de fördes? 4. Vem hjälper till? 5. Vem är ansvarig för gisslan? 6. Var söker de? 7. Vad påstod han att han skulle göra med gisslan? 8. Har han gjort det här? 9. Har det funnits några ledtrådar till var? 10. Finns det någon anledning att hitta dem? 11. Vad är det? 12. Vem måste besegras? 13. Varför är det svårt att hitta dem? 14. Vem talar om detta? 15. Finns det någon annan? 16. Vem ger råd? 17. Vem bekämpar terror? 18. Vem har lagt ut en video? 19. Vilken roll har han? 20. Hur länge har de varit försvunna? 21.
