The Islamic State (IS) group's affiliate in Egypt claimed responsibility for a rocket attack from the Sinai Peninsula into southern Israel on Friday.

"Three Grad rockets were fired at Jewish positions in occupied Palestine," the "Sinai Province" group said in a statement on Twitter.

The IS-linked group said the rocket fire was in retaliation for alleged Israeli support for Egypt's armed forces on Wednesday when they attacked army checkpoints in northern Sinai.

Two rockets fired landed in an open area of Eshkol regional council in southern Israel.
