Tanzanian President John Magufuli sacked two senior officials late on Monday after they failed to recall immediately how much money was allocated by the government in their respective districts for public road construction projects.
Magufuli, nicknamed "the Bulldozer" for his infrastructure projects and leadership style, launched his reform drive after he was elected in late 2015, promising to transform an economy hobbled by red-tape and corruption and carry out a major building program.
He has sacked thousands of civil servants over the past two years in a crackdown on government inefficiency and corruption.
A statement issued by the president's office said the sacked director of the Bukoba Municipal Council, Erasto Aron Mfugale, and the director of the Bukoba Rural Municipal Council, Mwantum Kitwana Dau, would be assigned to other duties.
The two dismissed officials were not immediately available for comment.
Magufuli, who served as the public works minister for nearly 20 years before becoming president, is widely known for having data at his fingertips, and frequently recites monetary figures and exact lengths of roads to their decimal points without referring to notes.
He has purged more than 20,000 "ghost workers" from the public service payroll and sacked 12,000 government employees for forging their academic transcripts.
"I will continue to straighten out those few people who have been looting this country in order to ensure that the majority of the population can reap the benefits," he said.
Magufuli has won praise from some Western donors for cracking down on corruption and tax evasion.
Critics accuse his administration of being increasingly autocratic, but the president declared on Monday that his government "respects democracy".
