President Bashar-al Assad

Ten members of the Group of 20 international economies joined the United States in accusing the Syrian government of carrying a chemical weapons attack on civilians last month and called for a strong international response against the regime of Syrian President Bashar Assad.

Syrian security forces killed at least 62 people Sunday in an escalation of the crackdown on protests ahead of the holy month of Ramzan, activists and residents said. Most died in raids on the flashpoint city of Hama, where a barrage of shelling and gunfire left bodies scattered in the streets.
