Khan Younis, Gaza - An Israeli strike killed six people and wounded around 20 at Nasser Hospital in southern Gaza, a civil defense official told AFP on Thursday.

The Israeli military confirmed the strike, claiming it targeted "a senior Hamas terrorist and additional terrorists from Hamas' military wing" operating from the hospital.

The Gaza Strip's civil defense, a rescue agency, said the bodies of those killed and "more than" 20 people wounded in the strike had been recovered from a building at the medical complex.

"The death toll from the Israeli strike inside Nasser Medical Complex, west of Khan Younis in southern Gaza, has risen to six," civil defense spokesperson Mahmoud Bassal told AFP.
