Yemen’s Houthi rebels are stepping up their missile attacks, keeping up what could be the last major front in the Middle East wars.

Israel launched a multi-wave attack across Yemen in retaliation for Houthi missile and drone strikes, the Israeli military confirmed Thursday.

Israel’s military says it intercepted a missile fired toward the country by Yemen’s Houthi rebels. The attack set off sirens late Monday in central areas of Israel, including Tel Aviv.

Tens of thousands of protesters took to the streets of Sanaa on Friday as part of a weekly demonstration in solidarity with Palestinians in the Gaza Strip. Those gathered waved flags, banners and rifles aloft as they chanted anti-American and anti-Israeli slogans.
