North Korean ballistic missile 'EXPLODES on its launch pad and severely injures staff' during botched test firing – the fourth failed attempt this year

A North Korean ballistic missile is believed to have exploded on its launch pad today in its latest botched test firing. Official sources said the blast is thought to have severely injured personnel working close to the medium-range weapon. It is the latest in a series of setbacks for a ballistic weapons programme that aspires to threaten the US mainland. 

South Korea's Yonhap news agency quoted official sources as saying today's missile may have exploded on its mobile launcher.

'The explosion is presumed to have inflicted serious injuries on personnel in the immediate vicinity,' Yonhap said.

South Korea's defence ministry detected the dawn launch effort which Japan condemned as an unacceptable and 'provocative' act.

The ministry declined to speculate on the missile type.

But military sources cited by local media said it was a powerful, medium-range 'Musudan' that has already undergone three failed launches this year. 

UN resolutions ban North Korea from any use of ballistic missile technology, although it regularly fires short-range missiles into the sea off its east coast.

Tuesday's effort came with tensions still running high on the divided Korean peninsula following the North's fourth nuclear test in January and long-range rocket launch a month later.

'We believe that it was a failure,' said Jeon Ha-Gyu, spokesman for the South Korean Joint Chiefs of Staff

'As to why and how it failed, we are in the process of analysing that,' Jeon told a press briefing.

'We are maintaining a strong defence posture with potential further provocations by the North in mind,' he added. 

In April, the North failed three times to test fire a Musudan, which has an estimated range of anywhere between 1,550 and 2,500 miles.

The lower range covers the whole of South Korea and Japan, while the upper range would include US military bases on Guam.

Japanese Foreign Minister Fumio Kishida said: 'North Korea's repeated ballistic missile launches are serious, provocative acts against the international community, including Japan.

'We absolutely cannot accept this,' Kishida said.

First unveiled as an indigenous missile at a military parade in Pyongyang in October 2010, the Musudan has never been successfully flight-tested.

The three failures in April were seen as an embarrassment for the Pyongyang leadership, coming ahead of a ruling party congress in May that was meant to celebrate the country's achievements.-Dailymail
