An Iron Dome battery was deployed in Ashdod on Thursday, following a defense assessment carried out by the Israel Defense Forces' Southern command.
A battery was deployed in the same area last month, after Palestinian prisoner Mohammed Allaan's health seriously deteriorated after 65 days on hunger strike.
Allaan was rearrested on Wednesday, following his release from the Barzilai Hospital in Ashkelon.
The Israel Defense Forces Spokesperson's Unit said Allaan was detained due to intelligence information.
A few hours after he was rearrested, Allaan's lawyer said he has resumed his hunger strike, and is under medical supervision at the prison.
