US-Mexico border: Number of migrant arrests in United States down

The number is down from 140,000 in May to 51,000 in August, according to US Customs and Border Protection preliminary figures.

The numbers of asylum seekers apprehended at the United States border with Mexico has dropped in recent months after Mexico agreed to halt the migrant flow in June – or face US economic sanctions.

Trump says the deployment of thousands of Mexican soldiers to the border has helped bring down the numbers.

But critics say the policy is not a long-term solution.
