LONDON (AP) — The heads of the American and British foreign intelligence agencies said Saturday they are “working ceaselessly” for a cease-fire in Gaza, using a rare joint public statement to press for peace.

CIA Director William Burns and MI6 Chief Richard Moore said their agencies had “exploited our intelligence channels to push hard for restraint and de-escalation.”

In an opinion piece for the Financial Times, the two spymasters said a cease-fire in Israel’s war against Hamas “could end the suffering and appalling loss of life of Palestinian civilians and bring home the hostages after 11 months of hellish confinement.”

Burns has been heavily involved in efforts to broker an end to the fighting, traveling to Egypt in August for high-level talks aimed at bringing about a hostage deal and at least a temporary halt to the conflict.

So far there has been no agreement, though United States officials insist a deal is close. U.S. President Joe Biden said recently that “just a couple more issues” remain unresolved. Israeli Prime Minister Benjamin Netanyahu, however, has said reports of a breakthrough are “exactly inaccurate."

The U.S. and the United Kingdom are both staunch allies of Israel, though London diverged from Washington on Monday by suspending some arms exports to Israel because of the risk they could be used to break international law.

Burns and Moore stressed the strength of the trans-Atlantic relationship in the face of “an unprecedented array of threats,” including an assertive Russia, an ever-more powerful China and the constant threat from international terrorism — all complicated by rapid technological change.

They highlighted Russia’s “reckless campaign of sabotage” across Europe and the “cynical use of technology to spread lies and disinformation designed to drive wedges between us.”

U.S. officials have long accused Moscow of meddling in American elections, and this week the Biden administration seized Kremlin-run websites and charged employees of Russian broadcaster RT with covertly funding social media campaigns to pump out pro-Kremlin messages and sow discord around November’s presidential contest.
