MOGADISHU, Somalia - The Latest on the explosion in Somalia's capital (all times local):

7:30 a.m.

Qatar's foreign minister says his country's diplomatic mission in Somalia was hit by the massive truck bombing in Mogadishu.

Sheikh Mohammed bin Abdulrahman Al Thani said on Twitter early Monday morning: "The attack on (hashtag)Qatar diplomatic mission in Mogadishu will not deter our support for (hashtag)Somalia's democracy, security and stability."

He did not elaborate. It was unclear if any Qataris were hurt in the blast. Officials in Doha did not immediately respond to a request for comment.

Somalia has found itself torn by the boycott by four Arab nations of Qatar.

Saudi Arabia is the Somali government's biggest benefactor, while the United Arab Emirates has trained the country's military and launched a high-profile aid appeal this year. Somalia has meanwhile allowed Qatari aircraft to increasingly fly through its airspace as Arab nations have closed theirs off.

A Somali state in September broke with Somalia's central government in Mogadishu, saying it backed the boycotting nations.
