More rain threatens US flood clean-up

More rain has fallen on Houston, threatening to complicate the clean-up after a long holiday weekend of storms and floods that left at least 17 dead and more than a dozen others missing in Texas and Oklahoma.

The forecast was for 2 to 3 more inches of rain in the Houston area, a day after flooding triggered by nearly a foot of rain in a matter of hours swamped neighbourhoods and highways and stranded hundreds of motorists.
