Relief teams are delivering aid to China Sichuan Province, two days after an earthquake killed at least 188 people and injured more than 11,000.
Reports said rescue teams used dynamite to unblock roads made impassable by landslides triggered by the quake.
The delivery of relief supplies, while not enough to meet all the demand, marked headway as frustrations grew among survivors.
Near an old house that had crumpled by the roadside in Lushan, about 2,000 people gathered early on April 22 to complain about the lack of food.
A few jumped onto a motorized three-wheel cart to look for officials, and 20 minutes later a truck pulled up and distributed instant noodles.
