Sana'a: Two men were killed and 25 injured when a hand grenade was thrown at a restaurant full of people, mainly students, during breakfast rush hour on Saturday near the gate of the University of Sana'a.

A student studying at the agriculture college was killed and the other succumbed to his injuries later in the hospital. The sources did not identify the second man who died at the hospital.

Mohammad Hassan, 30, surrendered to the security forces which quickly surrounded the area.

"Family differences were behind the attack," the official news agency, Saba, quoted an unidentified security official as saying.

Hassan held grudges with one of his relatives who works at the restaurant, the official said.

Sources at two hospitals, Republican and Kuwait hospitals, confirmed they had received about 25 injured people, including a child. Some of them were in critical condition and under intensive care.

Witnesses said Hassan lobbed the grenade near the door of the restaurant.

"While people, mostly students and bus drivers, were having breakfast, an unknown man came up and threw a hand grenade to the door of the restaurant," said a witness.

Meanwhile, the State Security Court sentenced yesterday a Yemeni to five years in prison for forging a passport to go to Iraq for purposes of jihad.

The court, chaired by Judge Muhsen Alwan, convicted Bashir Mohammad Ahmad No'man of being a member of Al Qaida.

The trial, one of the quickest, started last week when the prosecutor general accused No'man of forging a passport and impersonating his brother Sanad and using his passport to go to Iraq and lying to the authorities at Sana'a, Cairo and Damascus airports.

No man was arrested in Syria late last year and handed over to Yemen.
