MILWAUKEE (CBS58) -- All incoming flights to the United States from foreign countries will be subject to new security screening procedures. The new rules are to comply with government regulations to find hidden explosives in electronic devices. 

Travelers who pack any electronic device bigger than the average cell phone will need to take it out of their bags and place them on separate bins.

Travelers could also undergo stricter questioning at check in and at the boarding gate. 

The new security measures includes all airlines and affects 2,100 flights a day.
