Somalia claims s foreign country helped plan Saturday’s bomb explosion in Mogadishu that killed more than 90 people, the National Intelligence and Security Agency (NISA) said in a tweet on Monday.
The bombing was the deadliest in more than two years of violence in the country.
NISA said it would investigate the assault with help from a foreign intelligence agency.
No one has claimed responsibility for the bombing at the busy Ex-Control checkpoint in the northwest of Mogadishu, however, Mogadishu mayor Omar Muhamoud blamed al Qaeda-linked Islamist group al Shabaab.
The group carries out frequent bombings to try to undermine Somalia’s central government, which is backed by the United Nations and African Union peacekeeping troops.
The most deadly attack blamed on al Shabaab was in 2017 when a truck bomb exploded next to a fuel tanker in Mogadishu, killing almost 600.
