Italy's defense ministry said Tuesday that Hezbollah staged an attack on a U.N. peacekeeping base in Lebanon that it had blamed on Israel.

Defense Minister Guido Crosetto said that Israel on Tuesday staged an "intolerable" new attack on the U.N. peacekeeping force in Shamaa.

The Lebanese army said Israeli fire killed a soldier on Wednesday, a day after it said three other personnel were killed in a strike on their position in south Lebanon.

South Lebanon has seen intense fighting between Israel and Hezbollah.

U.S. mediator Amos Hochstein said Wednesday that he made "additional progress" in the Lebanon-Israel ceasefire talks after he held a second meeting with Speaker Nabih Berri.

Hezbollah said it carried out several attacks on Israeli troops near the border Wednesday.

Lebanon's official National News Agency reported Israeli shelling and air strikes in south Lebanon overnight and on Wednesday, saying Israeli troops were seeking to advance further near the town of Khiam.

Lebanese footballer Celine Haidar was about to make her dream of playing for the national women's team come true, but debris from an Israeli strike left the 19-year-old in a medically induced coma.

U.S. envoy Amos Hochstein was in Lebanon Wednesday, seeking to hammer out a ceasefire in the war between Israel and Hezbollah, as the militant group battled Israeli troops in the south of the country.

The Israeli military on Wednesday said it struck more than 100 "terror targets" in Lebanon over the past day and had "eliminated" two Hezbollah commanders at the weekend.

The targets included "launchers, weapons storage facilities, command centers, and military structures," the army said in a statement.

Four United Nations peacekeepers were wounded in southern Lebanon on Tuesday when a rocket struck a base, while another peacekeeping base was damaged by rocket fire and a patrol was shot at.

In a statement, the peacekeeping mission known as UNIFIL said “a rocket, likely fired by non-state actors within Lebanon,” struck the base of the Ghana's mission in the east of Ramia village, injuring four peacekeepers, three of whom required hospitalization.

The Lebanese Army said an Israeli airstrike targeted one of its military bases late Tuesday in the southern town of Sarafand, killing three Lebanese soldiers. The Health Ministry said at least 17 people were also wounded, including civilians who lived near the facility.

In total, 41 Lebanese soldiers have been killed amid the war between Israel and Hezbollah.

The U.N. peacekeeping chief says diplomatic efforts toward a cease-fire in Lebanon are “encouraging,” and that the United Nations is working on the role its peacekeeping mission in southern Lebanon could play after the Israel-Hezbollah war ends.

Jean-Pierre Lacroix, who just returned from Lebanon and Israel, told reporters Tuesday that the U.N. is proceeding on the basis that Security Council Resolution 1701, which ended the 2006 Israel-Hezbollah war, will remain the framework for a settlement .
