  Lyutikov (2002) predicted "radio emission from soft gamma-ray repeaters
(SGRs) during their bursting activity". Detection of a Mega-Jansky radio burst
in temporal coincidence with high energy bursts from a Galactic magnetar SGR
1935+2154 confirms that prediction. Similarity of this radio event with Fast
Radio Bursts (FRBs) suggests that FRBs are produced within magnetar
magnetospheres. We demonstrate that SGR 1935+2154 satisfies the previously
derived constraints on the physical parameters at the FRBs' loci. Coherent
radio emission is generated in the inner parts of the magnetosphere at $r< 100
R_{\rm NS}$. The radio emission is produced by the yet unidentified plasma
emission process, occurring during the initial stages of reconnection events.
