Israel will reopen its only crossing from Gaza for workers two days after closing it, the defence ministry said on Monday.

"Following a security assessment, it has been decided... that as of tomorrow... labourers and merchants will again be permitted to enter Israel from Gaza through the Erez crossing," said COGAT, a unit of the Israeli defence ministry responsible for Palestinian civil affairs.

The crossing is used by 12,000 Palestinians with permits to enter Israel for work.

"Opening the crossing for merchants and labourers and the other civilian measures applied to the Gaza Strip are conditioned on the continued preservation of a stable security situation in the area," COGAT said in a statement.

On Saturday, COGAT had announced it was closing Erez after militants in Gaza fired projectiles at Israel for four consecutive days, amid a second weekend of heavy clashes at east Jerusalem's flashpoint Al Aqsa mosque compound.
