Washington, October 1 (RHC)-- The U.S.-led bombing campaign in Iraq and Syria has seen its biggest day so far with British warplanes joining the attack. At least 24 strikes were launched between the two countries, where the Islamic State controls a vast stretch of territory.

Britain took part in the strikes for the first time since its Parliament voted to authorize the campaign on Friday. The strikes today have hit towns including Syria’s Kobani, which has come under a sustained Islamic State assault that has forced tens of thousands of Syrian Kurds to flee.

In other news, the White House has confirmed it has 'relaxed' standards aimed at preventing civilian deaths for the U.S. airstrikes in Iraq and Syria. According to reports from Washington, the Obama administration has acknowledged that a policy announced last year calling for "near certainty" of no civilian casualties in drone strikes will not apply to the current bombing.

The admission came in response to queries about a strike that killed up to a dozen civilians in the Syrian village of Kafr Deryan last week. The bodies of women and children were reportedly pulled from the rubble after a missile hit a home for displaced residents.
