An Israeli air strike Sunday hit one of Gaza's few functioning hospitals, killing a child, according to the World Health Organization, as Israel threatened with expanding its offensives.

Since the outbreak of war, tens of thousands of Palestinians in Gaza have sought refuge in hospitals, many of which have suffered severe damage in the ongoing Israeli attacks.

"A child died due to disruption of care" at the Al-Ahli Arab Hospital in northern Gaza after a strike, WHO chief Tedros Adhanom Ghebreyesus said on X.

Tens of thousands of Pakistanis filled the streets of Karachi to denounce Israel's war in Gaza and voice solidarity with besieged Palestinians.

Participants in the Gaza Solidarity March packed the city's main Shara-e-Faisal Road in the heat, waving Palestinian flags and holding portraits of Ismail Haniyeh and Yahya Sinwar, two top officials in Palestinian resistance group Hamas who were killed last year. Their images, flashing the victory sign, were also displayed on utility poles.
