Hungary's prime minister says he wants to speed up construction of a fence meant to stop migrants on the southern border with Serbia.

Orban was quoted Tuesday's edition of the pro-government Magyar Idok (Hungarian Times) daily newspaper as saying that he was persuaded of the need for more workers on the fence being built by the Hungarian army after an unannounced inspection of the barrier on Monday with his chief of staff, Janos Lazar.

Hungary initially said that a 4-meter (13-feet) high fence would be built on the 174-kilometer (109-mile) border with Serbia by the end of November, but in July Orban called for it to be completed by Aug. 31.

A government statement implied that Defense Minister Csaba Hende resigned Monday because of the unsatisfactory pace of construction.
