INTERNATIONAL NEWS - Students and school staff across the US are planning to commemorate the Florida school shootings with a walkout, exactly one month after the killings.
Organisers have called on them to stop lessons for 17 minutes in memory of the 17 people killed at Marjory Stoneman Douglas High School by a former pupil.
The walkouts are due to begin at 10:00 (10:00 EST is 14:00 GMT) across America's time zones.
Organisers accuse Congress of failing to tackle gun violence adequately.
The White House revealed a plan this week to deter school shootings which does not include President Donald Trump's repeated calls to raise the age for buying semi-automatic rifles to 21.
Instead, it moves ahead with his controversial proposal to provide firearms training to school employees.
