A US state is to enlist web users in its fight against illegal immigration by offering live surveillance footage of the Mexican border on the internet.
The plan will allow web users worldwide to watch Texas' border with Mexico and phone the authorities if they spot any apparently illegal crossings.
Texas Governor Rick Perry said the cameras would focus on "hot-spots and common routes" used to enter the US.
US lawmakers have been debating a divisive new illegal immigration bill.
The Senate has approved a law that grants millions of illegal immigrants US citizenship and calls for the creation of a guest-worker programme, while beefing up border security.
But in order to come into effect, the plan must be reconciled with tougher anti-immigration measures backed by the House of Representatives, that insist all illegal immigration should be criminalised.
The issue has polarised politics and US society. Right-wing groups have protested against illegal immigrants, while millions of people marched in support of them last month.
