    And in the day's other news, the Obama administration formally pledged to curb U.S. greenhouse gas emissions up to 28 percent over 10 years. It's part of a proposed global treaty. The cuts would come from vehicle and appliance efficiency standards and from limits on power plants. Some of those steps face challenges in Congress and the courts.

    The defense has rested in the Boston Marathon bombing trial, without calling the accused bomber, Dzhokhar Tsarnaev, to testify. His lawyers admit that he took part in the 2013 attack, but they're trying to save him from the death penalty. They called four witnesses to show that he was influenced by his brother. Closing arguments begin on Monday.

    Saudi Arabia's growing military campaign in Yemen intensified today, on land, sea and in the air.

    Jonathan Rugman of Independent Television News has this report.


    After six days of Saudi airstrikes, Yemen is on the verge of total collapse. So says the U.N., which adds that over 90 civilians have been killed here in the capital in the last few days, Saudi warplanes trying to drive Shia rebels back, but making enemies in the process.

  • MAN (through translator):

    They hit us until they completely destroyed these homes, while we were sleeping at home.


    In the north, a U.N. refugee camp was hit by Saudi jets, leaving at least 40 dead. The U.N. said it was shocked. Yemen's foreign minister blamed rebels for being there.

  • RIYADH YASEEN, Yemeni Foreign Minister:

    Houthis, they are going to places where there is some population or residential houses, and they're trying to put their weapons there.


    Last night, the Saudis hit this munitions warehouse near Sanaa. While the missiles are landing, the International Committee of the Red Cross has failed to negotiate delivering medical supplies by air, not in the midst of this burgeoning Sunni-Shia war.

    The Houthis are allied with Iran. And that alliance may strengthen, as the Saudi-led Arab coalition weighs up a possible land invasion next, because airstrikes may not be enough to dislodge them, and there's no sign of a political way out of this crisis, let alone a cease-fire.


    The Saudis say they mean to restore to office Yemen's president, Abd-Rabbu Mansour Hadi, who's also backed by the United States.

    President Obama today released military aid to Egypt, as the Cairo government moves to form an Arab alliance against terror. The aid had been on hold since the Egyptian military overthrew Islamist President Mohammed Morsi in 2013. It includes 12 F-16 fighter jets, plus missiles and other weaponry.

    In Iraq, government forces fought their way into the center of the city of Tikrit, against Islamic State militants. Military officials said troops attacking from the south and west have recaptured at least 75 percent of the city. The Interior Ministry reported street-to-street fighting, with at least 40 Islamic State fighters killed.

    Prime Minister Haider al-Abadi spoke in Baghdad.

  • HAIDER AL-ABADI, Iraqi Prime Minister (through translator):

    I would like to present to you the good news that our troops have raised the Iraqi flag over the provincial building.


  • HAIDER AL-ABADI (through translator):

    And they are now purging other parts of the city from the Islamic State militants.


    The operation to retake Tikrit began earlier this month, with Iranian support, but it stalled. Last week, the Iraqis called in U.S. airstrikes, and the ground offensive began moving again.

    The United States committed over half-a-billion dollars today to help Syrian refugees. It was part of nearly $4 billion pledged by nations at a U.N. summit in Kuwait. Almost 11 million people, half of Syria's population, have been displaced by the war.

    And back in this country, a late-day slide on Wall Street wiped out most of Monday's gains. The Dow Jones industrial average lost 200 points to close under 17800. The Nasdaq fell 46, and the S&P 500 gave up 18.
