China said on Wednesday it "firmly opposes" the escalation of military operations in Gaza after Israel launched a major ground assault on its largest urban hub aimed at crushing Hamas.
"China firmly opposes Israel's escalation of military operations in Gaza and condemns all acts that harm civilians and violate international law," foreign ministry spokesman Lin Jian said of the massive bombardment of Gaza City.
The Israeli military said on Wednesday it was opening an additional route for 48 hours that Palestinians could use to leave Gaza City as it stepped up efforts to empty the city of civilians and confront thousands of Hamas combatants.
Hundreds of thousands of people are sheltering in the city and many are reluctant to follow Israel's orders to move south because of the dangers along the way, dire conditions, a lack of food in the southern area, and fear of permanent displacement.
At least 30 people were killed across the Gaza Strip on Wednesday in Israel's latest strikes, including 19 in Gaza City, local health authorities said.
A day after Israel announced the launch of a ground offensive to seize control of Gaza's main urban center, tanks had moved short distances towards the city's central and western areas from three directions, but no major advance was reported.
An Israeli official said military operations were focused on getting civilians to head south and that fighting would intensify over the next month or two.
The official said Israel expected around 100,000 civilians to remain in the city, which would take months to capture, and the operation could be suspended if a ceasefire was reached with the Hamas group.
