A suicide bomber has killed at least 25 police recruits in Yemen.

Authorities say a device was set off as men queued at a recruitment centre.

The attack is the second this week and the so called Islamic State group has claimed responsibility.

15 troops died in an attack on Thursday.

Islamic State has also claimed responsibility for a suicide bomb attack at a gas plant in Baghdad.

At least 11 people were killed and 21 wounded.

A car bomb exploded at the entrance to the plant in the north of the Iraqi capital this morning.

Militants then rushed into the compound, setting off explosive vests.
