Hundreds of masked Hamas fighters brandishing assault rifles paraded in Gaza City and the group’s top leader made his first public appearance on Saturday, in a defiant show of strength after the militants’ 11-day war with Israel.

Saturday marked the first full day of a cease-fire, and Egyptian mediators held talks to firm up the truce which ended the fourth Israel-Hamas war in just over a decade.

In the fighting, Israel unleashed hundreds of airstrikes against militant targets in Gaza, while Hamas and other militants fired more than 4,000 rockets toward Israel.

In Gaza City, residents began assessing damage.

One of Gaza City’s busiest commercial areas, Omar al-Mukhtar Street, was covered in debris, smashed cars and twisted metal after a 13-floor building in its center was flattened in an Israeli airstrike. Merchandise was covered in soot and strewn inside smashed stores and on the pavement. Municipal workers swept broken glass and twisted metal from streets and sidewalks.

“We really didn’t expect this amount of damage,” said Ashour Subeih, who sells baby clothes. “We thought the strike was a bit further from us. But as you can see not an area of the shop is intact.” Having been in business for one year, Subeih estimated his losses were double what he has made so far.

Drone video and photos showed some city blocks reduced to rubble, in between homes and businesses left standing.

On Saturday, hundreds of Hamas fighters wearing military camouflage paraded past the mourning tent for Bassem Issa, a senior commander killed in the fighting. The top Hamas leader in Gaza, Yehiyeh Sinwar, paid his respects in his first public appearance since the war began.

Israel bombed the house of Sinwar, along with that of other senior Hamas figures, as part of its attack on what it said was the group’s military infrastructure. Israel’s defense minister, Benny Gantz, has said Israel delivered a punishing blow to Hamas, and that top Hamas figures remained targets.
