By Roberta Rampton WASHINGTON (Reuters) - President Barack Obama on Saturday defended his decision to allow Royal Dutch Shell to drill for oil in the Arctic Ocean under what he said were rigorous standards, fending off criticism by environmental groups. The trip is part of a broad campaign to seal an international deal later this year to curb carbon emissions, something the White House hopes will cap Obama's legacy on climate during his time in office. While Obama pushes the world to wean itself from fossil fuels, his administration gave Shell the green light earlier this month to drill in the oil-rich Chukchi Sea.
Police hunting for the perpetrators of Thailand's deadliest bombing arrested a suspect on Saturday they said fitted the description of a man seen on security cameras leaving a rucksack at the site of the Aug. 17 Bangkok blast. Police raided an apartment in a northern suburb of the capital on Saturday afternoon and discovered possible bomb-making materials that could have been used in the evening attack in Bangkok's bustling commercial heart. The bomb tore through the crowded Erawan Shrine, one of the country's top tourist attractions and close to high-end hotels and malls, killing 20 people and wounding scores more.
