Therapy of seizures

As a paramedic in a refugee camp, you are called to a child who has been suffering from generalized tonic-clonic convulsions for 20 minutes. After a brief interview with the mother, you find out that he is Amir of Yemeni origin, born approximately 8 months ago on the way from Yemen, but the mother does not know the exact date of birth. You question about the medication administered so far, but none has been given to Amir. He's not febrile, and you'll take a glucose meter to measure normoglycemia. What drug will you give Amir to terminate the seizure activity?
