Iran has launched a series of missiles at American military bases in the Middle East in retaliation for Sunday morning's US bombing raids.

Six missiles were sent towards the US-run Coalition Air Operations Centre at Al-Udaid in Qatar - which houses UK military personnel.

The base was already said to be at a state of "high readiness" for a strike from Iran.

The sounds of several explosions were heard over Qatari capital Doha just minutes after the missiles' launch, according to eyewitness reports.

While in Iraq, a "maximum alert status" has been declared at the Ain Al-Asad US base - with soldiers told to shelter in bunkers as a matter of urgency.
