KHARTOUM, Sudan — Sudan’s official news agency said a car exploded in a Red Sea port in the country’s east, killing one man Tuesday.

SUNA reported the blast took place at the entrance to Port Sudan, 680 kilometers northeast of the capital of Khartoum. It did not provide further details. The agency quoted police spokesman Maj. Gen. al-Sir Ahmed Omar as saying that police are investigating the cause.

Sudan is not known for any militant group that uses car bombs or similar tactics inside the country.

Sudanese officials hinted at Israeli involvement. Reuters quoted Sudanese Foreign Minister Ali Ahmed Karti saying the explosion resembled an April 2011 attack that Khartoum blamed on Jerusalem.

In April 2011, Sudan accused Israel of being behind an airstrike against a car driving along the coast in the Port Said area, in a case believed to involve weapons smuggling to militants in Gaza.

Port Said is the country’s main shipping port.

Israel’s Foreign Ministry had no comment. “I’m not going to respond to generic allegations,” spokesperson Yigal Palmor said.
