Israel has reopened two crossings into Gaza it shut after a rocket from the strip destroyed the home of a British-Israeli family north of Tel Aviv, injuring seven people.

The Kerem Shalom commercial crossing and Erez transit crossing reopened on Sunday morning, after huge protests on Saturday that marked the first anniversary March of Return protests in Gaza.

The crossings were closed last Monday, after rocket destroyed the home of British olim Robert and Susan Wolf, who made aliyah 30 years ago. Mrs Wolf and other members of their family were rushed to hospital after the blast.

Since then, Israel retaliated, striking Hamas targets in the strip, prompting another round of rocket fire in response.

On Saturday, tens of thousands took part in protests at the Gaza border at the first anniversary of the Great March of Return protests and clashed with Israeli forces.

The IDF said the border was attacked by people "armed with knives, explosives, and grenades".

Gaza's health ministry said four people - all males aged 17 ato 21 - were killed by Israeli forces. Haaretz reported at least 60 people were injured.
