A ceasefire between Israel and Hamas has begun following 11 days of fighting that have left more than 200 dead - the vast majority of them Palestinians.
Prime Minister Benjamin Netanyahu's office announced the ceasefire and a security cabinet statement called it "mutual and unconditional".
Hamas had confirmed that the truce would begin at 2am on Friday (midnight UK time).
Boris Johnson said he welcomed news of the ceasefire.
In a tweet, the prime minister said: "Leaders in the region must now work to find a durable solution to the Israeli-Palestinian conflict that prevents terrorism, ends the cycle of violence and delivers a sustainable and just peace."
As the ceasefire took effect, Palestinians left their homes and returned to the streets of Gaza. Some shouted "Allahu akbar", while others whistled from their balconies.
Cars packed the roads, with drivers honking their horns and waving flags from the windows. Some men fired rifles into the air, while others set off firecrackers.
