pakistan. we want to see a strong and stable pakistan but we cannot tolerate in any sense the idea dead the country is allowed to work both ways and is able to work the export of terror anywhere else in the world. >> the british prime minister there. rescuers said to a town in northeast china where flooding has trapped 13,000 people. it is believed that the reservoir in the province has overflowed. china is suffering its worst floods in decades. the prime minister has caused -- called the situation critical. >> engulfing several homes, coming to rest in this residential area.

campaign across the country. they will face far tougher opposition in southern spain and madrid. police in france have detained a couple in their 40's after the bodies of eight newborn babies were found in a house in the north of the country. christian frazier gave us more. >> what we are hearing from police is that they were tipped off about two of the bodies found in the garden by the new owners of the property. the skeletal remains of newborn babies, leading them to have property about a kilometer away for. -- away. they were all wrapped in bags. did did may have been going on since 1988. the couple arrested was in their '40's.
