Israeli authorities closed the Kerem Shalom and Erez crossings between Israel and the Gaza Strip on Monday for the Jewish Sukkot holiday.
An official at the Palestinian liaison department told Ma'an that more closures would follow in coming days during the eight-day Jewish festival, although he said the crossings would be open on Tuesday.
The crossings were partially open on Sunday.
On Monday, Israeli forces reportedly detained four Palestinians attempting to cross out of Gaza.
Earlier this month, the crossings were closed during the Jewish new year holiday as well the Yom Kippur holiday.
The Kerem Shalom crossing in southern Gaza is a vital entry point for goods into the Israeli-blockaded coastal territory, while Erez is the only crossing for people travelling between Gaza and Israel, although travel is heavily limited by Israeli authorities.
