In Yemen, a suicide bomber standing in a line of men at a police recruitment center near the southeastern port city of Mukalla exploded himself, killing at least 25 people and wounding 60 others.
Medical officials said those who survived the blast were transported to a local hospital.
IS posted a statement online claiming responsibility for the bombing, the second this week in Mukalla, which is generally known as a stronghold for rival Islamist group al-Qaida.
Forces of Yemen's internationally recognized government recaptured Mukalla last month from al-Qaida, which had controlled the city for a year.
On Thursday, IS claimed responsibility for a suicide attack on a naval camp that killed 10 soldiers and wounded another 15.
