Kuwait on Wednesday said Iranian attacks on its territory killed one person and wounded several others, as well as forcing its airport to close and damaging unnamed diplomatic missions.

Kuwait's foreign ministry condemned the attacks "that once again targeted vital and civilian infrastructure, including Kuwait International Airport, killing one person and injuring others, in addition to causing damage to vital infrastructure including diplomatic missions".

Israeli Prime Minister Benjamin Netanyahu announced on Tuesday allocations of 13 billion shekels (more than $4.5 billion) to secure and develop northern communities along the Lebanon border, battered by weeks of fire from Iran-backed Hezbollah.

"The government made dramatic decisions today to strengthen the north. We are investing more than 13 billion shekels today, in addition to the seven billion we have already provided -- a total of 20 billion shekels going to the communities of the north," Netanyahu said following the government's approval of the measure.

Israeli strikes on southern Lebanon on Tuesday killed five people, including a child, and wounded 48, the Lebanese health ministry said.

Israeli Prime Minister Benjamin Netanyahu on Tuesday said Israel would help to make Iran's "terror regime" disappear, as talks to reach a peace agreement between the U.S. and the Islamic republic appeared to stutter.

Israel and Lebanon could reach a peace agreement within days were it not for the obstacle posed by Hezbollah, U.S. Secretary of State Marco Rubio said Tuesday, as the two sides began a fourth round of talks in Washington.

"Israel and Lebanon can do a peace deal tomorrow," Rubio told the Senate Foreign Relations Committee.

Hezbollah will not accept a "partial ceasefire" with Israel, a senior official from the Iran-backed group said Tuesday, refusing to halt attacks against northern Israel in exchange for Israel sparing Beirut's southern suburbs, although they appeared to have stopped on Tuesday.

In a south Lebanon hospital heavily damaged by deadly Israeli strikes nearby, Dr Nasser al-Masri held a new-born baby, calling him "a message of life and hope" despite the war.
