MOGADISHU—Islamist group al Shabaab on Monday claimed responsibility for a bomb blast in Mogadishu that killed at least 90 people over the weekend while Somalia said a foreign government that it did not identify helped plan the attack.

The bombing was the deadliest in more than two years in a country wrecked by nearly three decades of Islamist violence and clan warfare.
