Lawyers representing a Gaza hospital director detained in an Israeli raid late last year say an Israeli court has extended his detention for another six months.
Israeli troops detained Dr. Hossam Abu Safiya when they raided Kamal Adwan Hospital in December.
He was held without access to a lawyer for 47 days and has not been charged, according to Al Mezan, a human rights group representing him in court.
Al Mezan said the Beersheba District Court issued the order extending his detention on Tuesday.
It said prosecutors submitted secret evidence alleging he is a threat to Israeli security, allegations he denies.
There was no immediate comment from the Israeli military.
Israel has raided hospitals in Gaza on several occasions during the 17-month war with Hamas, accusing the group of using them for military purposes.
Hospital staff deny the allegations and accuse Israel of recklessly endangering civilians.
