The sudden flare-up in Gaza between Palestinian militant groups and Israel is another grim reminder that the situation in the blockaded Mediterranean strip remains precarious. The latest violence was triggered by a botched spy operation by Israeli commandos inside Gaza that killed seven Palestinians, including a Hamas military commander. Hamas, which controls the territory and Islamic Jihad fired hundreds of rockets and mortar shells into Israel in retaliation. Israel responded with airstrikes and artillery fire, hitting scores of military posts and weapons depots across Gaza. They levelled television and radio stations as well as Hamas's military intelligence headquarters. It was the heaviest Israeli attack since the 2014 war on the impoverished enclave of 1.82 million people. Now, Gaza is staring at the prospect of a fourth war in a decade.
