Venezuelan police detained a university student outside the US Embassy on Monday, saying he left two low-intensity explosives on the street outside the diplomatic mission. No one was hurt, and the student's motives remained unclear.
Police set off the homemade devices - essentially large fireworks - while they closed the street to traffic outside the embassy. Children were evacuated from an adjacent school.
Wilfredo Borraz, police chief for the Baruta section of Caracas, told reporters that one of the explosives was found outside the school and one inside a planter about 50 meters (yards) from the embassy entrance.
He said both were in black plastic bags and contained "small fliers with publicity alluding to Hizbullah" - the Lebanese guerrilla group.
