CAIRO — An explosion ripped through a checkpoint in Egypt's restive Sinai Peninsula on Thursday, killing three soldiers and a police officer, while Egyptian officials sought to put the best face on a U.S. move to cut hundreds of millions of dollars in military assistance.
Meanwhile, Egyptian authorities said two Canadian nationals who were jailed for seven weeks and released this week were free to leave the country. Filmmaker John Greyson and physician Tarek Loubani were arrested in mid-August during a government crackdown on followers of the Muslim Brotherhood, who were demanding the reinstatement of ousted President Mohammed Morsi.
The two had described harsh conditions in jail, and the case became an embarrassment for Egyptian officials. The men had hoped to board a flight out within hours of their release early Sunday, but were prevented from doing so.
Egypt's military campaign in Sinai, which has intensified in the last month, targets Islamist militant groups that the government says became entrenched in the peninsula during Morsi's yearlong rule. The Islamist president was overthrown July 3 and is now facing trial.
Thursday's blast, which also left four members of the security forces injured, took place near El Arish, an area of northern Sinai that has been the scene of frequent clashes between militants and police and soldiers.
Counterterrorism efforts in Sinai are among the measures that are to be spared in the U.S. military-aid cuts, which were announced Wednesday in Washington.
"This decision is taken at a time when we are facing terrorism," said Badr Atty, an Egyptian Foreign Ministry spokesman. "We think it's an incorrect decision, but the U.S. is committed to preserving and maintaining a long-standing partnership with Egypt. It's a temporary decision."
Operations in Sinai are a highly sensitive issue for Egyptian authorities. A prominent Egyptian journalist working there was recently imprisoned for a month and handed a suspended six-month suspended sentence after the army accused him of lying about its activities and traveling without permission into a closed military zone.
The peninsula is the scene of near-daily violence. On Wednesday, four soldiers were hurt when their vehicle drove past a roadside bomb, Egyptian authorities said. That same day, a bomb went off in a military intelligence office in Rafah, bordering the Gaza Strip, but the office was empty at the time.
