At least one rocket hit a camp in Iraq housing Iranian dissidents, officials and the group based there said Wednesday, after Baghdad and the U.N. signed a pact to resettle its residents.

The United States on Tuesday accused Syria of having intensified attacks against its people before Arab observers arrived in the country to monitor a deal to end nine months of deadly violence.

Saboteurs blew up a gas pipeline in the flashpoint Syrian region of Homs on Tuesday, the official SANA news agency reported, as Arab League observers visited the provincial capital.
