The Israeli military said Wednesday it had killed six gunmen in an updated toll from an exchange of fire in Gaza the day before, accusing them of violating the ceasefire in the territory.
The military said in a statement late on Tuesday that it had killed two of six fighters it had identified adjacent to its troops in western Rafah and that tanks had fired on them.
It said they were killed in an ensuing exchange of fire, including aerial strikes, while troops continued to search for the rest.
In a statement on Wednesday, the military said that "following searches that were conducted in the area, it is now confirmed that troops eliminated the six terrorists during the exchange of fire".
It said the presence of the gunmen adjacent to troops and the subsequent incident were a "blatant violation of the ceasefire agreement".
A security source in Gaza reported late on Tuesday that Israeli forces had "opened fire west of Rafah city".
Under a truce that entered into force in October following two years of war between Israel and Hamas, Israeli forces in Gaza withdrew to positions behind a demarcation known as the "yellow line".
The city of Rafah is located behind the yellow line, under Israeli army control. The area beyond the yellow line remains under Hamas authority.
Both sides have repeatedly accused the other of violating the ceasefire.
According to the health ministry in Gaza, which operates under Hamas authority, at least 165 children have been killed in Israeli attacks since the ceasefire began on October 10.
The UN children's agency UNICEF said on Tuesday that at least 100 children -- 60 boys and 40 girls -- had been killed since the truce.
Israeli forces have killed a total of at least 447 Palestinians in Gaza since the ceasefire took effect, according to the ministry.
The Israeli army says gunmen have killed three of its soldiers during the same period.
