The Israeli defence ministry has hailed a “breakthrough” in the development of cheaper laser-based air defences, as tensions soar in the region after Iran hit US targets in retaliation for a high-profile assassination. The lasers, still under development, would be capable of intercepting “everything” fired at Israel, including long and medium range missiles, rockets, mortar rounds and drones, an official told AFP on Thursday, asking not to be identified. The new technology, which Israel hopes to test later this year, uses electricity to power the lasers, doing away with the need for stocks of munitions, the official said.
