Israel's defence minister has resigned over the cabinet's decision to accept a ceasefire ending two days of fighting with Palestinian militants in Gaza.
Avigdor Lieberman denounced the move as "surrendering to terror".
He said his right-wing Yisrael Beiteinu party would leave the ruling coalition, which could lead to an early election.
Eight people were killed on Monday and Tuesday as militants fired 460 rockets towards Israel and Israeli forces bombed 160 targets in Gaza.
The ceasefire was largely holding on Wednesday and schools and businesses in southern Israel reopened after no rocket attacks were reported overnight.
However, Israel's military said it had shot at and captured a Palestinian man who tried to breach the Israel-Gaza border fence while hurling grenades.
Palestinian health officials later said a fisherman had been killed by Israeli fire in northern Gaza.
The Israeli military said soldiers had shot the man because he was advancing towards the border fence.
