Lima: Holding photos of Peruvian Agence France Presse photographer Jaime Razuri, Peruvian journalists attend a vigil calling for his release at the Palestinian diplomatic office in Lima.

Palestinian gunmen abducted Razuri in Gaza on January 1.

Palestinian authorities indicated on Friday there were signs of progress in the probe into Razuri's abduction, but refused to give details in order to avoid compromising the investigation.
