Is­raeli airstrikes Sat­ur­day killed at least 11 peo­ple and in­jured dozens in cen­tral Beirut, of­fi­cials said, as diplo­mats scram­bled to bro­ker a cease-fire.

Lebanon’s Health Min­istry said the death toll could rise as emer­gency re­spon­ders dug through the rub­ble look­ing for sur­vivors. DNA tests are be­ing used to iden­ti­fy the vic­tims, it said, adding that 63 peo­ple were wound­ed. The strikes were the fourth in the Lebanese cap­i­tal in less than a week.

The es­ca­la­tion comes af­ter U.S. en­voy Amos Hochstein trav­eled to the re­gion this week in an at­tempt to bro­ker a cease-fire deal to end the more than 13 months of fight­ing be­tween Is­rael and Hezbol­lah, which has erupt­ed in­to full-on war in the past two months.

Is­raeli bom­bard­ment has killed more than 3,500 peo­ple in Lebanon and wound­ed more than 15,000, ac­cord­ing to the Lebanese Health Min­istry. The fight­ing has dis­placed about 1.2 mil­lion, or a quar­ter of Lebanon’s pop­u­la­tion. On the Is­raeli side, about 90 sol­diers and near­ly 50 civil­ians have been killed by rock­ets, drones and mis­siles in north­ern Is­rael and in fight­ing in Lebanon.

Is­rael’s war with Hamas al­so shows no signs of abat­ing. Gaza’s health min­istry said at least 80 peo­ple were killed be­tween Thurs­day and Fri­day in mul­ti­ple strikes in the en­clave’s north, in­clud­ing the Ka­mal Ad­wan and Al-Ahli hos­pi­tals. Dozens of peo­ple are still trapped un­der the rub­ble, it said.
