UNITED NATIONS, Aug. 25 (Xinhua) -- UN Secretary-General Antonio Guterres on Monday strongly condemned the killing of Palestinians in Israeli strikes that hit Nasser Hospital in Khan Younis, Gaza, said his spokesman.

Those killed, in addition to civilians, included medical personnel and journalists, said Stephane Dujarric, the spokesman, in a statement.

"These latest horrific killings highlight the extreme risks that medical personnel and journalists face as they carry out their vital work amid this brutal conflict," he said. "The Secretary-General recalls that civilians, including medical personnel and journalists, must be respected and protected at all times. He calls for a prompt and impartial investigation into these killings."

The UN chief reiterated that medical personnel and journalists must be able to perform their essential duties without interference, intimidation or harm, in full accordance with international humanitarian law, said Dujarric.

Guterres also reiterated his call for an immediate and permanent ceasefire, unfettered humanitarian access across Gaza, and for the immediate and unconditional release of all hostages, said the spokesman. ■
