Mexico: Panic alarms installed to protect schools

Teachers in the Mexican resort of Acapulco have decided to end a month-long strike after they reached an agreement on new security measures with the city's authorities.
The police will strengthen security patrols around school buildings and install panic alarms to protect teachers and pupils from organised crime.
It comes after drug gangs left five severed heads outside a school in Acapulco earlier this week.
