For the first time in months, air raid sirens sounded in Sderot and other communities near the Gaza border on Thursday night, according to media reports.
No injuries or damage were reported, but local residents said they heard a loud explosion, as a rocket apparently from Gaza, landed in an open field.
When the sirens wailed, people rushed for shelter.
“We closed the door and there was a strong explosion. It must have been a Qassam, I have no doubt because I recognize the sound,” one southern resident told Ynet.
“It took us by surprise and we only had a few seconds to realize what was happening because we are in a period of calm; we were unprepared. We received no special directives since then,” he added.
The code red siren was the first since December 20, breaking the ceasefire with Hamas.
Security forces were searching for remnants of the projectile, the IDF said.
None of the terrorist groups in Gaza had taken responsibility for the attack as of late Thursday night.
