Israeli airstrikes killed more Islamic Jihad militants in Gaza on Wednesday as rocket fire toward Israel resumed after a brief overnight lull, raising the death toll in the strip to 16 Palestinians in the heaviest round of fighting in months. The Israeli military said more than 250 rockets have been fired at Israeli communities since the violence erupted following an Israeli airstrike that killed a senior Islamic Jihad commander accused of being the mastermind of recent attacks. Israel has stepped up its battle against Iran and its proxies across the region.
