The Israeli military said Friday it had struck more than 3,500 targets across Lebanon in the month since fighting with the Hezbollah group began.
Lebanon was drawn into the Middle East war on March 2 after Iran-backed Hezbollah launched rockets at Israel to avenge the US-Israeli attack that killed Iran's supreme leader Ali Khamenei.
Israel has responded with massive strikes across Lebanon and a ground offensive.
The Israeli military said Friday it had killed approximately 1,000 militants in Lebanon over the past month, with strikes targeting what it described as "terrorist infrastructure, weapons storage facilities, launch positions, and command and control headquarters" belonging to Hezbollah.
Lebanon's health ministry said on Thursday that 1,345 people had been killed and 4,040 wounded since the start of the war, including 1,129 men, 91 women and 125 children.
The ministry said the toll also included 53 healthcare workers.
Hezbollah has so far not announced its losses.
On Thursday, Israeli Defense Minister Israel Katz warned that Hezbollah chief Naim Qassem would pay an "extraordinarily heavy price" for escalating attacks during the ongoing Jewish holidays.
"The Hezbollah terrorist organization you now lead, and its supporters in Lebanon, will bear the full and severe consequences," Katz said.
His warning followed claims by Hezbollah that it had carried out a series of rocket attacks on northern Israel late Wednesday and early Thursday, as Israeli Jews began marking Passover.
Katz also reiterated that Israeli forces "will clear Hezbollah and its supporters from southern Lebanon, maintain Israeli security control throughout the Litani area, and dismantle Hezbollah's military capabilities across Lebanon".
Eighteen European countries on Thursday urged Israel and Hezbollah to stop fighting as their latest conflict reached one month and with fears over Israeli plans to occupy part of southern Lebanon post-war.
"Israeli military operations in Lebanon and Hezbollah's attacks must cease," the foreign ministers of the countries including Italy, Spain, Belgium, Poland and Ireland said in a joint statement.
"We urge Israel to fully respect Lebanon's sovereignty and territorial integrity, and call on all parties, both Hezbollah and Israel, to halt military action," the statement said.
The countries include Spain, Austria, Belgium, Croatia, Cyprus, Estonia, Finland, Iceland, Italy, Ireland, Latvia, Luxembourg, Moldova, Norway, Poland, San Marino, Slovenia and Sweden.
