  Since its early phases of operation, the AGILE mission is successfully
observing Gamma Ray Bursts (GRBs) in the hard X-ray band with the SuperAGILE
imager and in the MeV range with the Mini-Calorimeter. Up to now, three firm
GRB detections were obtained above 25 MeV and some bursts were detected with
lower statistical confidence in the same energy band. When a GRB is localized,
either by SuperAGILE or Swift/BAT or INTEGRAL/IBIS or Fermi/GBM or IPN, inside
the field of view of the Gamma Ray Imager of AGILE, a detection is searched for
in the gamma ray band or an upper limit is provided. A promising result of
AGILE is the detection of very short gamma ray transients, a few ms in duration
and possibly identified with Terrestrial Gamma-ray Flashes. In this paper we
show the current status of the observation of Gamma Ray Bursts and Terrestrial
Gamma-ray Flashes with AGILE.
