Yemeni security forces have arrested a 20-year-old female student in Sanaa, the country's capital, on suspicion of sending explosives stuffed in printer cartridges on cargo planes bound for the US.

The packages, which were addressed to synagogues in Chicago, were discovered early on Friday in London and Dubai.

The discoveries have put global air security on high alert.
