Prime Minister Benjamin Netanyahu said Tuesday that Israel was continuing to pound Iran and vowed to hit Hezbollah with increasing force as the war in the Middle East raged for a fourth day.

"We continue to strike Iran with force. Our pilots are over the skies of Iran and Tehran, and also over the skies of Lebanon. Hezbollah made a very big mistake when it attacked us. We have already responded forcefully, and we will respond with even greater force," Netanyahu said at an air force base in central Israel, according to a statement from his office.
